Morphology
infinitival = infinitive (semi-transparent) = infinitiv + al
The adjective is regularly formed from the grammatical term 'infinitive' plus '-al', but the base term is specialized linguistic vocabulary rather than a highly transparent everyday word.
Etymology
Infinitival comes from infinitive, which has the parts in- 'not' and finite 'finished', so it originally means 'not finished', the basic or 'unfinished' form of a verb. A helpful way to remember is that an infinitival phrase is about that basic verb form you often see with 'to', so infinitival means 'about or using the infinitive form'.
