Etymology
The word 'approximately' has its roots in the Latin verb 'approximare', meaning 'to come near to'. This verb itself is built from 'ad-' (to) and 'proximus' (nearest, superlative of 'prope' meaning near). The core concept of 'nearness' has been preserved throughout its evolution. Entering English in the 17th century via the past participle 'approximate', the adverbial form '-ly' was added to create a term that logically describes an action or state done in a manner that draws near to, but does not fully reach, exactness or precision.
Analysis
'ap-' is a Latin prefix (ad-) meaning 'to, toward'. 'proxim' is from Latin 'proximus' meaning 'nearest, very near'. '-ate' is a Latin suffix used to form verbs or adjectives. '-ly' is an Old English suffix used to form adverbs.
