एकाएक (ekaaek)

adverb A single-sense adverb meaning 'suddenly, all of a sudden' -- used to describe an abrupt, unexpected change or event.
Sense 1 : suddenly, all at once
adverb
Synonyms: अचानक (achaanak), अकस्मात (akasmaat, literary), सहसा (sahsaa, literary), झटपट (jhatpat, quickness of action rather than surprise)
Frequency: medium
Cultural Note: You will hear this a lot in narrated stories or news reports -- 'एकाएक बारिश शुरू हो गई (ekaaek baarish shuroo ho gaii, 'suddenly it started raining')' has a slightly more dramatic, literary color than the everyday अचानक (achaanak), though both are perfectly common in speech. The word is literally built from एक (ek, 'one') doubled, giving a sense of 'in one single instant.'
Common Mistakes: 1) Learners often reach only for अचानक (achaanak) and never encounter एकाएक (ekaaek), but the two are freely interchangeable in speech -- एकाएक (ekaaek) just sounds slightly more literary or narrative, as in storytelling or news reports. 2) It describes the suddenness of an event, not the speed of an action -- don't use it where English 'quickly' (not 'suddenly') is meant.
