देर (der)

noun/adverb Mainly a feminine noun meaning 'delay' or 'a while (of time)', used constantly in everyday speech about being late or about duration; also works as an adverb-like predicate in fixed phrases like देर होना (der honaa) and देर करना (der karnaa).
Sense 1 : delay, lateness
noun, feminine Most common in the fixed construction देर होना (der honaa, 'to become late') with a को-marked experiencer, and देर करना (der karnaa, 'to make a delay/take too long').
Synonyms: विलंब (vilamb, formal), देरी (derii)
Frequency: high
Cultural Note: You will hear देर हो गई! (der ho gaii, 'it's gotten late!') shouted in almost every Delhi household when someone is dawdling before school, work, or a wedding baraat (baaraat) -- lateness is framed as something that happens to you, matching the involuntary-verb pattern learners see with लगना (lagnaa).
Common Mistakes: 1) Learners often say मैं देर हूँ (main der hoon) intending 'I am late', but Hindi uses the dative-subject frame मुझे देर हो गई (mujhe der ho gaii, 'I got late') -- देर (der) is the thing that 'happens to' you, not a state you 'are'. 2) देर करना (der karnaa) means 'to delay/take long' (as in delaying an action), while देर होना (der honaa) means 'to become/get late' (as in the time itself slipping) -- learners often mix these two up.
Sample Sentences:
देर हो गई, चलो जल्दी करो! It's gotten late, come on, hurry up!
(der ho gaii, chalo jaldii karo!)

Sense 2 : a while, a span of time
noun, feminine Used in phrases like कुछ देर (kuchh der, 'for a little while') or देर तक (der tak, 'for a long time/until late'), quantifying duration rather than describing lateness.
Synonyms: समय (samay), वक़्त (vaqt)
Frequency: high
Cultural Note: देर तक (der tak, 'until late') is what you say when describing staying up late chatting over chai (chaay) with friends -- it stretches the same word from 'lateness' into plain duration, so listen for तक (tak) or कुछ (kuchh) nearby to tell which sense is meant.
Common Mistakes: 1) कुछ देर (kuchh der) means 'for a little while' (a short duration), which learners sometimes confuse with the 'lateness' sense -- here देर (der) is neutral duration, not a complaint about being late.

Register: Casual -- Mood: Indicative -- Aspect: Continuous -- Tense: Past -- Voice: Active

Sense 3 : late (in time)
adverb Functions adverbially in phrases like देर से आना (der se aanaa, 'to come late'), where देर से (der se) literally means 'from/after a delay'.
Synonyms: विलंब से (vilamb se, formal)
Frequency: high
Cultural Note: देर से आना (der se aanaa, 'to come late') is basically the national pastime excuse for missed trains and parties -- delhiites will cheerfully say थोड़ी देर से आऊँगा (thodii der se aaoongaa, 'I'll come a bit late') without much guilt, since 'IST' is jokingly reinterpreted as 'Indian Stretchable Time'.
Common Mistakes: 1) Learners often drop से (se) and just say देर आना (der aanaa) intending 'to come late', but the natural adverbial form requires से (se): देर से आना (der se aanaa).
Sample Sentences:
