बुद्धि (buddhi)

noun Refers to the intellect or mind's capacity for reasoning, judgment, and understanding -- a feminine noun with one core sense, though it appears in several fixed idioms about thinking clearly (or not).
Sense 1 : intellect, intelligence, reasoning faculty
noun, feminine
Synonyms: अक्ल (akl), समझ (samajh), मेधा (medhaa, literary), प्रज्ञा (pragyaa, literary)
Frequency: medium
Cultural Note: बुद्धि (buddhi) carries a slightly more elevated, almost classical flavor than अक्ल (akl) -- it's the word you'll hear in a school context ('बुद्धि का विकास', buddhi kaa vikaas, 'development of intelligence') or in a proverb, whereas अक्ल shows up more in everyday scolding like 'तेरी अक्ल कहाँ गई' (terii akl kahaan gaii, 'where has your sense gone'). Ganesh is traditionally called 'बुद्धि के देवता' (buddhi ke devtaa, 'the god of intellect'), which gives a sense of how the word is tied to wisdom and auspicious beginnings in Hindu culture.
Common Mistakes: 1) Learners often reach for अक्ल (akl) in every context since it is more common in casual speech; बुद्धि (buddhi) is the word to use when talking about intellect in a more formal, philosophical, or educational register -- for example describing a child's cognitive development or a person's analytical mind, rather than street-smart cleverness. 2) बुद्धि (buddhi) is grammatically feminine even though it refers to an abstract mental faculty -- don't default to masculine agreement just because the concept feels abstract.
