What does explicatory mean?
'Explicatory' is a formal adjective describing something that serves to explain or interpret — commentary, notes, essays, or remarks whose purpose is to make a difficult text or idea clear. It derives from the Latin verb explicare, meaning 'to unfold' or 'to lay open', the same source that gives us 'explicit', 'explicate', and 'explication'. Though its meaning is virtually identical to that of the everyday word 'explanatory', 'explicatory' carries a distinctly scholarly register: it tends to surface in literary criticism, philosophy, and textual scholarship rather than casual conversation. A reader might encounter it in phrases such as 'explicatory notes' or 'an explicatory essay'. Because it is rare, using it signals erudition, but writers should be aware that 'explanatory' communicates the same idea with greater clarity for most audiences.

Etymology of explicatory
'Explicatory' comes from the Latin explicare, meaning 'to unfold, unroll, or spread out', formed from ex- ('out') and plicare ('to fold'). The metaphor is one of unfolding something folded up so it can be seen plainly — hence, explaining it. English adopted the word via related forms such as 'explicate' and 'explication', which entered the language in the early modern period, with 'explicatory' appearing somewhat later as a derivative adjective. It shares this Latin root with 'explicit' and 'explicative', all preserving the sense of laying something out clearly.
How explicatory is actually used
'Explicatory' is formal and relatively rare; it appears mostly in academic, literary-critical, or religious-scholarly writing, where it often overlaps with 'exegetical'. In general prose, 'explanatory' is the standard choice.
