Definition
Meaning
A plural noun referring to 1) the metal pieces used in the game of jacks, 2) mechanical devices for lifting heavy loads, or 3) (capitalised) a name or nickname.
Can also refer to electrical/telephone sockets (UK: 'phone jack'), playing cards of rank between ten and queen, a type of fish, a small flag on a ship, or the ball in lawn bowls. The singular form 'jack' has many more meanings (e.g., car jack, jack of all trades, a male donkey). The word 'jacks' is primarily used for the children's game or multiple lifting devices.
Linguistics
Semantic Notes
'Jacks' is lexically plural but can refer to a single game set. The singular 'jack' in the game context is rare (e.g., 'pick up the jack'). The game sense is more common in North America. It functions as a plural noun and a 3rd person singular verb (he jacks up the car).
Dialectal Variation
British vs American Usage
Differences
In the UK, 'jacks' for the children's game is less common; the game is often called 'five stones' or 'knucklebones'. 'Jack' for a socket (e.g., 'phone jack', 'headphone jack') is common in both. The verb 'to jack (up)' (to lift) is used in both varieties.
Connotations
In the US, 'playing jacks' evokes childhood nostalgia. In the UK, the term is more often associated with the lifting device or electrical connections.
Frequency
The game sense is significantly more frequent in American English. The 'socket' sense is equally frequent, though often in compound nouns.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводите 'jacks' (игра) как 'джексы' без контекста. Игра часто не имеет прямого перевода – опишите: 'детская игра с металлическими фигурками и мячиком'.
- 'Car jack' – это не 'домкрат' (это 'hydraulic jack'), но 'jack' часто используется как общий термин. 'Jack' в картах – это 'валет'.
- Глагол 'to jack up' (поднимать домкратом) не имеет отношения к имени 'Jack'.
Common Mistakes
- Using 'jacks' as a singular noun (e.g., 'I need a jacks' – incorrect; should be 'I need a jack').
- Confusing 'jacks' (game/tool) with 'Jax' (a name or brand).
- Incorrect pluralisation: 'jack' -> 'jacks' is correct; no 'jackses'.
