महा- (mahaa-)

adjective A bound prefix meaning 'great' or 'mega-,' attached to nouns and adjectives to intensify or elevate them; it never stands alone as a word.
Sense 1 : great, mighty, supreme (prefixed to a noun)
adjective Attaches directly to the following noun with no space in careful spelling, e.g. महापुरुष (mahaapurush, 'great man'), महाशक्ति (mahaashakti, 'superpower'); the compound as a whole then behaves as an ordinary noun.
Synonyms: बड़ा (badaa, separate word, not a prefix), परम (param, literary)
Frequency: high
Cultural Note: You will meet this everywhere from mythology to modern media: महाभारत (mahaabhaarat, the great epic), महात्मा (mahaatmaa, 'great soul,' as in Mahatma Gandhi), and even casual exaggeration like महामूर्ख (mahaamoorkh, 'a huge fool'). It carries the same instinct as English 'mega-' or 'super-' but with a more classical, weighty flavor drawn from Sanskrit.
Common Mistakes: 1) Learners sometimes write it as a free-standing word with a space before the noun it modifies, like महा पुरुष (mahaa purush); in standard usage it is fused: महापुरुष (mahaapurush). 2) महा- (mahaa-) itself never inflects for gender or number -- only the noun it attaches to does.
Sample Sentences:

Sense 2 : used ironically/humorously to mock exaggerated importance
adjective The prefix itself doesn't change form for this sense; the ironic tone comes entirely from context and the noun chosen, e.g. महाज्ञानी (mahaagyaanii, 'ever so wise,' said sarcastically).
Synonyms: तथाकथित (tathaakthit, so-called, more formal)
Frequency: medium
Cultural Note: Delhi friends love this move: calling someone महाज्ञानी (mahaagyaanii) or महारानी (mahaaraanii, 'queen,' used sarcastically toward someone acting entitled) is a classic gently teasing jab, similar to English 'oh, Your Highness.' The literal grandeur of महा- (mahaa-) is what makes the sarcasm land.
Sample Sentences:
अरे महारानी, अब उठ भी जाओ, दोपहर हो गई है। Oh, Your Highness, get up already, it's afternoon now.
(are mahaaraanii, ab uth bhii jaao, dopahar ho gaii hai।)
