divertimento [I], divertissement [F]—amusement, diversion, entertainment, even table music; Typically, a suite of movements (often more than 4), often intended for diversion and pleasure of a lighthearted nature, suitable for social occasions. Typically implies a smaller chamber ensemble. The name was common in the 18th century for a variety of music, some of which was more serious and profound than its title would suggest.

moderato [I], moderamente, modéré [F], modérément [F]—moderately, at a moderate tempo, applying a touch of restraint to its related word(s), e.g. allegro moderato
opus [L], opera[pl], Op., Opp, WoO, Op. posth—work, as in a work of art. For unique identification, publishers/composers often assign an "opus number", abbreviated as "Op." (e.g. Op. 1). A range of works by opus number, uses the plural "opp." (e.g. "Opp. 1-3"). A single opus number may refer to a collection of works (e.g. a set of quartets) giving rise to designations like "Op. 1, No. 4". For misc. works without opus numbers, "WoO" is often used (e.g."Without Opus"). Posthumously assigned numbers may use "Op. posth". Opus numbers may not precisely reflect chronology (publication vs. composition), can be erroneous, sparse or duplicative. Thus, the works of some historically important composers may use separate catalog numbers (e.g. Bach, Haydn, Schubert). See wiki
quintet, quintette [F], quintett [G], quintetto [I]—an ensemble / work for 5 players, the typical examples being string quintet (with second viola or cello), piano quintet or woodwind quintet
