A knitting pattern is written in a shorthand that assumes you already know it. Nothing about it is intuitive, but almost all of it is standardised, which means the vocabulary is finite and worth learning once.
Abbreviations and where the master list lives
The industry reference is the Craft Yarn Council’s knitting abbreviations master list, which collects the abbreviations used by yarn industry designers and publishers: k2tog for knit two together, ssk for slip slip knit, psso for pass slipped stitch over, yo for yarn over, M1 for make one, and so on through the alphabet.
Two caveats on that page matter more than the list itself. First, the definitions reflect US knitting terminology, which is not identical to UK usage. The most notorious divergence is in crochet, where a US single crochet is a UK double crochet, but knitters meet it too: what Americans call gauge, British and Canadian patterns call tension. Second, designers and publishers routinely use special abbreviations that do not appear on the master list, and a definition of those is normally given at the start of the book or pattern. If a pattern uses something you have never seen, look for its own special abbreviations section before assuming it is standard.
Repeats, brackets and asterisks
The punctuation is doing real work. An asterisk marks a starting point for a repeat, so a line reading star k2, p2, repeat from star to end means work those four stitches over and over until the row runs out. Two asterisks usually mark a second, nested starting point in the same row.
Brackets and parentheses group instructions. Square brackets followed by a number, such as k1, yo, k1 in brackets twice, mean work everything inside the brackets that many times. Parentheses more often carry either a stitch count check at the end of a row, or the alternatives for different sizes.
Size specific numbers are the single most common source of error. A pattern written for five sizes will read cast on 88, 96, 104, 112, 120 stitches, with the smallest first and the rest in parentheses. Before you start, go through the whole pattern with a highlighter and mark every number for your size. Doing that once takes ten minutes and eliminates an entire category of mistake.
Charts and reading direction
Charts are pictures of the fabric as it faces you from the right side, with one square representing one stitch and one horizontal line of squares representing one row or round. Row numbers appear at the edges, and the numbering starts at the bottom right, because that is where the knitting starts.
For flat knitting, read right side rows from right to left, and wrong side rows from left to right. That reversal is the part people forget, and it is what the row number position tells you: a number on the right edge means the row is read from that side. For knitting in the round, every round is a right side round, so every round is read right to left with no reversal at all.
Bold or coloured lines inside a chart mark the pattern repeat. Stitches outside those lines are edge stitches worked once at the beginning and end of the row, and the section between them is repeated as many times as the stitch count allows.
Symbols, and what a symbol means on the wrong side
Lace charts use symbols for the operations rather than for the result: a circle for a yarn over, a right leaning or left leaning slash for a decrease that leans that way, a triangle for a double decrease. Cable charts use blocks with crossing arrows showing which group of stitches passes in front.
The rule that catches everyone out is that a chart symbol describes what the stitch looks like from the right side, not what your hands do on the row you are working. A blank square meaning a knit stitch on a right side row means purl it when you meet it on a wrong side row, because purling from the back produces a knit stitch on the front. Every chart carries a key, and the key will state this explicitly, usually as knit on right side rows and purl on wrong side rows. Read the key before the chart.
Skill levels and what they predict
The Craft Yarn Council also standardises difficulty. Its project level definitions run from Basic, meaning projects using basic stitches that may include basic increases and decreases, through Easy, which may include simple stitch patterns, colour work or shaping, and Intermediate, which may include involved stitch patterns, colour work or shaping, up to Complex, where a project may combine complex stitch patterns, colour work and shaping using a variety of techniques and stitches simultaneously.
Read those definitions carefully and you will notice they describe technique count and how much is happening at once, not difficulty of execution. A complex level lace shawl may be entirely straightforward if you are comfortable with charts and have a lifeline in place. An easy sweater can be miserable if it requires a seaming method you have never done. Use the label to predict what skills the pattern will call on, then check whether you have them, rather than treating it as a verdict on whether you can manage.
