कल (kal)

adverb/noun One of Hindi's most useful time words: it means both 'yesterday' and 'tomorrow' (context tells you which), and separately, as a noun, it means 'peace/comfort/ease' (mostly seen in the idiom कल न पड़ना (kal n padnaa)).
Sense 1 : tomorrow
adverb
Frequency: high
Cultural Note: This dual meaning trips up almost every beginner at least once -- कल (kal) really can mean 'yesterday' or 'tomorrow' in the very same sentence shape, and Hindi speakers simply lean on the verb's tense to tell them which. If you want zero ambiguity, pair it with आने वाला (aane vaalaa, 'coming') or बीता हुआ (biitaa huaa, 'past') in careful speech, though in casual conversation people rarely bother.
Common Mistakes: 1) कल (kal) alone is ambiguous between 'yesterday' and 'tomorrow' -- native speakers rely entirely on the verb tense in the sentence to disambiguate, so listen for the tense, not the word. 2) Learners sometimes add a redundant time postposition; कल (kal) functions adverbially on its own and normally takes no postposition, e.g. कल आऊँगा (kal aaoongaa, 'I will come tomorrow'), not कल में (kal men).

Sense 3 : peace, ease, comfort
noun, feminine Almost always seen in negative constructions, especially कल न पड़ना (kal n padnaa, 'to have no peace/rest') and चैन से कल न आना (chain se kal n aanaa).
Synonyms: आराम (aaraam), चैन (chain)
Frequency: low
Cultural Note: You'll mostly meet this कल (kal) in the idiom कल न पड़ना (kal n padnaa) -- something like 'I can't rest easy until...' -- which a worried mother might say about a child who hasn't called home, or a shopkeeper about an unpaid debt.
Common Mistakes: 1) This कल (kal) is a completely different word from the time-adverb sense, even though it looks identical -- it means 'peace' or 'rest,' not 'yesterday/tomorrow,' and only really surfaces in a small set of fixed phrases like मुझे कल नहीं पड़ती (mujhe kal nahiin padtii, 'I get no peace').
Sample Sentences:
