Etymology: "Lactations" is simply the plural of "lactation," the process by which a mammal produces milk. The base word traces to Latin "lactātiō," a noun formed from "lactāre," meaning to suckle or to give milk, itself built on "lac," the Latin word for milk. English took the term as a learned borrowing, so it reached the language through scholarly and medical writing rather than everyday speech, which is why it sounds more technical than its plainer cousins. The ending "-ation" is a Latin noun-forming suffix that turns a verb into a name for the act or process it describes, and "lactate" supplies the verb stem. The same pattern gives English words like "creation" and "formation." "Lactate" is the older verb, so "lactation" is a process noun built on it rather than the other way round.
