सब (sab)

adjective/pronoun सब (sab) is a common all-purpose quantifier meaning 'all/everyone/everything' -- it works as an adjective before a noun and as a pronoun standing on its own.
Sense 1 : all, every (modifying a noun)
adjective
Synonyms: सारा (saaraa), तमाम (tamaam), पूरा (pooraa, whole)
Frequency: high
Cultural Note: You will hear सब (sab) constantly in everyday Delhi speech -- सब ठीक है (sab thiik hai, 'everything is fine') is practically a national reflex answer to 'how are things'.
Common Mistakes: 1) सब (sab) itself does not inflect, but when used with a plural noun the noun and verb still take normal plural agreement: सब लड़के (sab ladke, all the boys), not a special form of सब (sab). 2) Learners sometimes add लोग (log) redundantly out of habit -- सब (sab) alone before a noun is already 'all', though सब लोग (sab log, everyone) is also fine and extremely common.

Sense 2 : everyone, everything (standing alone)
pronoun Used without a following noun, सब (sab) stands in for 'everyone' (people) or 'everything' (things) depending on context, and takes plural verb agreement: सब आ गए (sab aa gae, 'everyone has arrived').
Synonyms: सभी (sabhii), सारे (saare)
Frequency: high
Cultural Note: सब कुछ (sab kuchh) is a set phrase you'll hear in emotional contexts too -- like जीवन में सब कुछ (jiivan men sab kuchh, 'everything in life') -- so it's worth learning as a chunk rather than building it from scratch each time.
Common Mistakes: 1) Whether सब (sab) means 'everyone' or 'everything' is decided entirely by context -- there is no marking on the word itself, which can confuse learners expecting a grammatical cue. 2) सब कुछ (sab kuchh, 'everything') is the fixed way to unambiguously say 'everything'; bare सब (sab) alone often defaults to 'everyone' in conversation about people.
