Easy to mix with look-alikes
The spelling risk for 3D is neighbouring look-alikes ("3M", "3P", …), not just typos; it is anadjective. Frequency #3,203. Gloss: "Abbreviation of three-dimensional.".
3D has no tracked misspelling variants, since its letter pattern doesn't lend itself to common typo substitutions. It also participates in 4 confusable-pair relationships, "3M", "3P", "3rd", and more, since the words sound or look close enough that writers reach for the wrong one mid-sentence.
This entry carries no recorded etymology, so its spelling is easiest to reason about phoneme by phoneme, absent a documented history. The correct English form is 3D, spelled 3-D.
