More about lacustrine

The adjective lacustrine, “relating to a lake; living or growing in lakes,” is a technical term used in geology (lacustrine strata, lacustrine deltas) and biology (lacustrine plants, lacustrine fauna). Lacustrine comes from French or Italian lacustre “relating to a lake” and the naturalized English adjective suffix –ine. The French and Italian adjectives are irregularly formed from Latin lacus “lake, pond, pool,” and the Latin adjective suffix –estris, –estre, on the analogy of Latin palustris, palustre “swampy, marshy,” formed from palūs “swamp, fen.” Lacustrine entered English in the first half of the 19th century.

More about sartorial

The adjective sartorial, “relating to tailors or tailoring,” is a derivative of the Late Latin noun sartor (inflectional stem sartōr-) “a tailor,” a derivative of the verb sarcīre “to patch, mend.” One of the many duties of Roman censors was to let out contracts for the repair and maintenance of public buildings, roads, bridges, etc., the technical phrase for these operations being sarta tecta (neuter plural) “repairs,” literally “mended roofs, patched roofs, weatherproof buildings.” But as Rome’s power grew, so did opportunities for corruption in the competition for lucrative contracts. Sartorial entered English in the first half of the 19th century.
