मत (mat)

particle/noun Two distinct words sharing this spelling: a negative particle used to form prohibitions ('don't'), and a noun meaning 'opinion' or 'vote/doctrine'.
Sense 1 : negative prohibitive particle ('don't')
particle Placed directly before the verb, typically with the imperative stem: मत जाओ (mat jaao, 'don't go'). Cannot be used to negate a statement of fact -- that job belongs to नहीं (nahiin).
Synonyms: न (n, more formal/literary in prohibitions), नहीं (nahiin, used differently -- see CommonMistakes)
Frequency: high
Cultural Note: A parent telling a child मत करो (mat karo, 'don't do that') is one of the most-heard phrases in any Indian household -- मत (mat) is the everyday word for 'don't' in speech, direct and immediate, while न (n) tends to feel a notch more formal or literary in the same role.
Common Mistakes: 1) Learners sometimes reach for नहीं (nahiin) to form a command, producing नहीं जाओ (nahiin jaao), which sounds wrong to a native ear -- मत (mat) is the word Hindi actually reserves for negative commands. 2) मत (mat) pairs naturally with the plain imperative (जाओ (jaao)) or subjunctive-flavored forms, not with the past tense -- you cannot use it to say 'you didn't go.'
Sample Sentences:
मत जाओ! Don't go!
(mat jaao!)

Sense 2 : opinion, view, doctrine, vote
noun, masculine
Synonyms: राय (raay), विचार (vichaar, slightly more formal), सम्मति (sammti, literary)
Frequency: medium
Cultural Note: This noun shows up constantly in civic and political vocabulary -- मतदान (matdaan, 'voting') and मतदाता (matdaataa, 'voter') build directly on this मत (mat, 'vote/opinion'), so recognizing it here unlocks a whole family of election-season words.
Common Mistakes: 1) मत (mat) in the sense of 'opinion' is largely a written/formal-register word; in casual speech राय (raay) is far more natural for 'what do you think?' -- मेरी राय में (merii raay men, 'in my opinion') is much more common than मेरे मत में (mere mat men).
