Shortening of Kwajalein.
American English is usually spoken by Kwajalein island's American expatriate population, which has the father-bother merger; for accents without this merger (including Received Pronunciation), /ˈkwɒdʒ/ is a possible realization. This is not technically wrong, because the aforementioned father-bother merger makes this pronunciation indistinguishable from /ˈkwɑːdʒ/. Indeed, the name of the island's primary hotel, the Kwaj Lodge, is a word play on Kwaj and lodge rhyming.
- (colloquial) Kwajalein island; Kwajalein atoll.

- In locative context, the phrase "on Kwaj" is far more common than "in Kwaj".
