मालूम (maaloom)

adjective/verb An adjective/predicate-complement word meaning 'known' -- almost always used with होना (honaa) 'to be known/aware' or पड़ना (padnaa) 'to find out, come to know', both in dative-subject constructions.
Sense 1 : known, aware (of something)
adjective Used almost exclusively with होना (honaa) in the pattern X को Y मालूम है (X ko Y maaloom hai) -- 'X knows Y', literally 'Y is known to X'. The knower is marked with को (ko), not the subject of an active verb.
Synonyms: पता (pataa), ज्ञात (gyaat, formal/literary)
Frequency: high
Cultural Note: This is the classic 'knowledge is something that is known to you' construction in Hindi -- the knower never actively 'does' the knowing, they simply have the state applied to them via को (ko). You'll hear मुझे मालूम है (mujhe maaloom hai, 'I know') constantly in everyday Delhi conversation, often with a shrug, as a slightly more considered alternative to मुझे पता है (mujhe pataa hai).
Common Mistakes: 1) Learners often try to use मालूम (maaloom) like a verb ('main maaluum karataa huun'), but it is not a verb -- it pairs with होना (honaa) or पड़ना (padnaa), never conjugates on its own. 2) मुझे मालूम है (mujhe maaloom hai, 'I know') is often confused with मुझे पता है (mujhe pataa hai) -- both are correct and largely interchangeable, but मालूम (maaloom) tends to feel slightly more formal/considered than the very casual पता (pataa).

Sense 2 : to find out, come to know, learn (something)
verb, intransitive Occurs in the fixed compound मालूम पड़ना (maaloom padnaa) or मालूम होना (maaloom honaa) meaning 'to come to know, to turn out (that)', with the experiencer marked by को (ko) and पड़ना (padnaa) carrying the sense of a fact 'landing on' or being discovered by someone.
Synonyms: पता चलना (pataa chalnaa)
Frequency: medium
Cultural Note: Where मालूम होना (maaloom honaa) with a static sense just states a known fact, adding पड़ना (padnaa) shifts the flavor toward a fact suddenly becoming known or a first impression forming -- close to English 'it turns out' or 'it seems.'
Common Mistakes: 1) मालूम पड़ना (maaloom padnaa) can also mean 'to seem, to appear' (e.g. 'यह ठीक मालूम पड़ता है' (yah thiik maaloom padtaa hai, 'this seems fine')) -- learners sometimes miss this 'seem' shade and only think of it as 'find out.'
