Morphology

formic + acid

Formic acid is a straightforward adjective+noun compound: it denotes an acid of the ‘formic’ type, so a learner who knows the adjective 'formic' and the noun 'acid' can infer it is a specific kind of acid. This follows regular compositional and scientific naming patterns (cf. Spanish 'ácido fórmico', French 'acide formique'), making the meaning directly derivable rather than idiomatic.

Etymology

Formic acid comes from the Latin word formica, which means 'ant'. Scientists found the sharp, sour liquid inside ants and some plants, so the name now means the acid those animals make and the chemical used in industry.
