tail end
Synonym discussion
Sense: noun/1
All of these point to where something stops, but they differ in tone and scope. 'End' is the plain, all-purpose word and simply marks where something finishes. 'Tail end' is more vivid and slightly informal: it stresses the very last, often small or fading portion — the tail end of a meeting is its dull final minutes. 'Conclusion' is formal and suggests a planned, rounded finish, common in essays and reports. 'Close' is gentle and often used for periods of time, as in 'the close of the day'. 'Finale' is reserved for a grand or dramatic ending, like the finale of a concert. You might say, 'We caught the tail end of the show, but missed the spectacular finale.'
Common collocations
Etymology
The phrase joins 'tail', from Old English 'tægel' meaning the rear growth on an animal, with 'end'. Because an animal's tail is its rearmost part, English speakers began using 'tail end' for the very back or final portion of anything — a line of people, a stretch of time, or, jokingly, the part of the body one sits on.
