Abbreviation & Stitch Glossary

Knitting & Crochet

Last updated: April 16, 2026

Searchable glossary of knitting and crochet abbreviations with US/UK toggle, stitch descriptions, and step-by-step diagrams.

Why You Need an Abbreviation & Stitch Glossary

Halfway through a vintage pattern, you hit “sl1-k2tog-psso” and freeze — what does that mean? Knitting and crochet patterns rely on over a hundred standard abbreviations, and designers sometimes invent their own. Without a reliable reference, one misread abbreviation can derail an entire project.

The confusion doubles when you cross the Atlantic. UK and US crochet terminology uses the same words for completely different stitches, so a British pattern calling for double crochet produces a fundamentally different fabric than the American stitch of the same name. A searchable glossary with a US/UK toggle eliminates this guesswork entirely.

What Is an Abbreviation & Stitch Glossary?

An abbreviation glossary is a searchable database of knitting and crochet abbreviations paired with their full names, definitions, and step-by-step execution instructions. It covers standard abbreviations published by the Craft Yarn Council as well as widely used designer shorthand for cables, colorwork, and lace.

The US/UK toggle switches the entire glossary between American and British terminology. Each entry shows the equivalent abbreviation in the other system when one exists, making it possible to work confidently from patterns published in either country.

The pattern translator feature goes further — paste a full instruction line and the glossary expands every abbreviation into plain language. This is especially useful for complex stitch sequences where multiple abbreviations stack together in a single instruction.

How UK/US Term Conversion Works

The UK/US conversion is not random — it follows a systematic offset. Every UK crochet term is one step higher than its US equivalent. UK double crochet equals US single crochet. UK treble equals US double crochet. UK double treble equals US treble. The entire naming ladder shifts by one rung.

This offset exists because UK terminology counts the loops on the hook, while US terminology counts the yarn overs before insertion. A US single crochet has zero yarn overs before inserting; the UK calls it double crochet because there are two loops on the hook after pulling up. Understanding this logic makes the entire conversion table predictable rather than something to memorize.

How to Use the Abbreviation & Stitch Glossary

Type any abbreviation into the search field to find its full name, description, and step-by-step execution. The glossary covers both knitting and crochet abbreviations. Use the US/UK toggle to switch between American and British terminology — the glossary shows the equivalent abbreviation in the other system when one exists.

Each entry includes a written description of how to work the stitch, the stitch symbol used in charts, and for common stitches, a step-by-step diagram. Browse by category (increases, decreases, basic stitches, cables, colorwork) or search directly.

Understanding Your Results

The US/UK toggle shows the equivalent term in the other system. "dc" in US crochet means double crochet (yarn over, insert hook, pull up loop, yarn over, pull through two, yarn over, pull through two). "dc" in UK crochet means what Americans call single crochet — a completely different stitch. The toggle makes this distinction explicit so you can work from any pattern regardless of its country of origin.

Some abbreviations have no direct equivalent in the other system and are flagged as such. Proprietary stitch abbreviations invented by individual designers are not included — those are defined within the pattern itself.

Pro Tips

From 30+ years of fiber arts experience

  • Always check the abbreviation key printed in your specific pattern before relying on the glossary. Some designers define custom abbreviations or use standard abbreviations in non-standard ways.
  • UK and US crochet terms are completely different for the same stitch. UK double crochet = US single crochet. UK treble = US double crochet. This single fact causes more pattern confusion than any other.
  • When an abbreviation is ambiguous and you cannot find a pattern key, look at the stitch count for the row. The stitch count tells you what the abbreviation must mean in context.
  • Save or bookmark the specific entries you need for your current project so you can reference them quickly without searching each time.

How to Read This Chart

This glossary contains searchable entries for over 100 standard knitting and crochet abbreviations paired with their full stitch names and execution instructions. Each entry shows the abbreviation (such as 'dc' for double crochet), the full stitch name, the complete sequence of movements to execute the stitch, the chart symbol, and any special technique variations. The US/UK toggle switches all entries between American and British terminology — selecting 'UK' remaps every crochet abbreviation, because 'dc' means double crochet in US but single crochet in UK. Categories organize by stitch family (basic stitches, increases, decreases, cables, colorwork, lace) for browsing by type. Each entry shows yarn overs before insertion, loops on hook at each stage, and turning chain counts for crochet stitches.

Industry Standards

The Craft Yarn Council (CYC) publishes the official standard abbreviations for North American knitting and crochet patterns, establishing the baseline set used by nearly all commercial US and Canadian patterns. In the UK, similar standards follow British fiber publications. The most significant divergence is UK crochet terminology, which systematically offsets stitch names by one step from the US system — UK 'double crochet' equals US 'single crochet,' UK 'treble' equals US 'double crochet.' This offset dates to early 20th-century pattern-writing traditions where the two countries counted hooks and loops differently. Individual designer shorthand for complex stitch sequences is common in indie patterns and vintage sources, which is why every pattern should include an abbreviation key.

Real-World Variations

Although CYC publishes standard abbreviations, individual designers and publishers sometimes deviate, particularly for complex stitches or specialty techniques. Vintage patterns from the mid-20th century often use abbreviations since redefined — 'yo' (yarn over) once appeared as '* yo' with an asterisk in some older sources. Regional knitting styles also create variations — continental European patterns sometimes use completely different shorthand than UK or US sources. Some abbreviations appear in one craft but not the other, or mean different things in each — 'sl st' (slip stitch) is executed completely differently in knitting versus crochet. Published pattern abbreviation keys should always be your primary reference.

Edge Cases & Exceptions

What does SSK mean in knitting?

SSK stands for Slip, Slip, Knit. It’s a left-leaning decrease where you slip two stitches knitwise one at a time, then knit them together through the back loops.

What does SC mean in crochet?

SC stands for Single Crochet (US term). In UK patterns, the same stitch is called DC (Double Crochet). This is one of the most common sources of confusion between US and UK patterns.

What’s the difference between US and UK crochet terms?

US and UK crochet terms are offset by one. A US Single Crochet = UK Double Crochet. A US Double Crochet = UK Treble. Our glossary shows both with a UK/US toggle.

What does FLO mean?

FLO stands for Front Loop Only. Instead of working through both loops of a stitch, you insert your hook or needle through only the front loop. This creates a ridged texture.

How do I read a knitting pattern?

Use our Pattern Translator. Paste a line from your pattern and every abbreviation gets highlighted with its full meaning. It’s like a real-time dictionary for pattern instructions.

What does YO mean?

YO stands for Yarn Over. You wrap the yarn around your needle to create a new stitch and a decorative hole. It’s the foundation of lace knitting.
