What does formicate mean?
Formicate is an exceedingly rare English verb whose roots lie in the Latin formica, meaning 'ant'. In its original sense it denotes the kind of restless, swarming motion characteristic of ants — creatures that seem to seethe and teem wherever they gather. The word survives only marginally, if at all, in modern usage, largely because it is so easily mistaken for its near-twin 'fornicate', which refers to sexual intercourse and shares nothing of the ant-related lineage. A related and genuinely living descendant of the same Latin root is 'formication', the clinical term for the eerie sensation of insects crawling on one's skin, familiar from discussions of stimulant misuse and certain neurological conditions. Anyone encountering 'formicate' today should read it cautiously: it may reflect an archaic entomological sense, or simply a slip of spelling for 'fornicate'.

One letter separates 'fornicate' from 'formicate' — and mixing them up turns a talk about ants into a very different conversation.

Etymology of formicate
Formicate descends from the Latin verb formicare, itself derived from formica, 'ant', which also gave us formic acid and the noun formication. The Latin verb described creeping or swarming like ants, and English borrowed this sense, though the word never became established. Its modern history is dominated by confusion with 'fornicate', a wholly separate word of different origin whose similarity of sound has all but eclipsed it.

How formicate is actually used
This is an extremely rare word, and many modern references treat occurrences of it as errors for 'fornicate'. Its root sense ties it to the swarming movement of ants rather than to anything sexual.
Easily confused with formicate
Fornicate means to engage in sexual intercourse outside marriage, whereas 'formicate' derives from the Latin formica (ant) and relates to creeping or swarming like ants — the two words look and sound deceptively similar.
Formication is the medical term for the hallucinated sensation of insects crawling on or under the skin; 'formicate' would be a verb form built from the same Latin root, not that condition itself.
