सहसा (sahsaa)

adverb A single-sense adverb meaning 'suddenly, all at once' -- a bookish, literary alternative to the everyday अचानक (achaanak).
Sense 1 : suddenly, all of a sudden
adverb
Synonyms: अचानक (achaanak), एकदम (ekdam), अकस्मात (akasmaat, literary)
Frequency: literary
Cultural Note: You will meet सहसा (sahsaa) far more in a novel, a news report, or a poem than in kitchen or market chat -- it has a slightly literary, narrative flavor, like saying 'all of a sudden' in a story rather than 'suddenly' in conversation. For everyday speech, अचानक (achaanak) is what people actually reach for.
Common Mistakes: 1) Learners often reach for this word in casual speech where अचानक (achaanak) is what a native speaker would actually say; सहसा (sahsaa) shows up mainly in writing, narration, or slightly formal speech. 2) It is invariant -- it never changes form regardless of the gender or number of the subject.
