Morphology

ad + hoc

Ad hoc is a borrowed Latin phrase (ad + hoc) whose constituents are not English lexical items that a B1 learner will typically know, so its meaning 'for a particular purpose' cannot be derived from familiar English words. Although the literal Latin 'to this' loosely relates to 'for this purpose', the expression is conventionalized as a fixed loanword in English and therefore is not transparently compositional for typical learners.

Etymology

Ad hoc: The adjective ad hoc comes from Latin words ad 'to' and hoc 'this'. So it describes something made for one special purpose and not planned before.
