M1R — Make 1 right-leaning (Abbreviation)
M1R exists as its own explicitly named abbreviation for one reason: patterns that shape both sides of a raglan seam, a yoke, or any other symmetrical increase line need two increases that point in opposite directions, and "make 1" alone doesn't specify which way. M1R is the half of that pair that leans right; M1L covers the left-leaning half.
Placement in a typical raglan or yoke pattern
M1R commonly shows up worked just after a marker rather than before it, angled so its lean points back toward the seam line it's helping shape — check the specific pattern's own placement instructions though, since which side gets M1R versus M1L, and exactly where relative to the marker, varies by designer rather than following one universal rule.
The mechanics, reversed from M1L
Everything about M1R's working motion mirrors M1L's, in both direction and result: where M1L lifts the connecting strand front-to-back and knits through the back loop, M1R lifts the identical strand back-to-front instead, and knits through the front loop of what's now sitting on the needle. Reversing both the lift direction and the insertion point together is what flips the finished stitch's lean from left to right rather than changing only one variable.
Why both reversals matter, not just one
Changing only the lift direction, or only which loop gets knit into, without changing the other, doesn't reliably produce a clean mirror of M1L — both halves of the motion need to flip together for M1R to actually read as M1L's true opposite in the finished fabric, rather than an inconsistent, oddly twisted stitch that's neither one nor the other.

FAQ
Is there a visual way to tell, after the fact, whether a stitch was made as M1L or M1R? Yes — look closely at which direction the stitch's base leans relative to its neighbors; a right-leaning M1R visibly tilts the opposite way from a left-leaning M1L once both are a row or two old and have settled into the fabric.
Would swapping M1L and M1R throughout an entire pattern change the finished size? No — swapping which lean goes on which side doesn't change the total stitch count or the rate of shaping, only which direction each individual increase visually points; the garment's overall size and fit stay the same either way.
