Definition
Meaning
The hindmost part of an animal's body that extends beyond the trunk.
Any long, thin, projecting or hanging part, often at the rear or end of something; the final or less important section of something; to follow closely and secretly; in law, a limited form of ownership.
Linguistics
Semantic Notes
The word exhibits a core-to-extension radial polysemy. From the prototypical animal body part, meaning extends to any rear/lower/hanging part (e.g., shirt tail), then to the end or conclusion of an event (tail of the storm), then to following someone (verb). The financial/law senses are specialized.

Connotations
Similar. 'Tail' can imply something less important or secondary (e.g., 'the tail of the distribution'). The verb can have a negative connotation of spying.
Frequency
The noun is equally frequent. The verb (to follow) is common in detective/police contexts in both varieties.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'tale' (story) which is a homophone. 'Tail' is 'хвост'. 'Tail verb' (to follow) is 'преследовать, следить'. The idiom 'turn tail' is specific; direct translation ('повернуть хвост') does not convey 'to flee'.
Common Mistakes
- Incorrect spelling: 'tale' for the body part. Confusing 'tail' (end) with 'trail' (path/ to drag behind). Using 'tail' as a verb without an object incorrectly: 'He was tailing.' (requires 'He was tailing the car.')
