के (ke)

postposition The oblique/masculine-plural form of का (kaa), Hindi's genitive ('of') postposition; it also shows up fixed inside several common conjunctive/pattern expressions like के बाद (ke baad) and के लिए (ke lie).
Sense 1 : possessive/genitive marker (before masc. plural or oblique nouns)
postposition Agrees with the following noun: का (kaa) before masc. singular, की (kii) before feminine, के (ke) before masc. plural or when the following noun is in the oblique case (e.g. before another postposition).
Frequency: high
Cultural Note: Think of का/के/की (kaa/ke/kii) as one team: के (ke) is simply the form that shows up when the 'owned' noun is masculine plural, like मेरे बच्चे (mere bachche, 'my children'), or whenever the possessive phrase itself needs to be in the oblique to host a further postposition, as in लड़के के घर में (ladke ke ghar men, 'in the boy's house').
Common Mistakes: 1) Learners often try to use के (ke) generically instead of switching to का (kaa) or की (kii) depending on the noun that follows it -- the choice depends on the noun owned, not the owner. 2) Because के (ke) also appears frozen inside के लिए (ke lie, 'for') and के बाद (ke baad, 'after'), learners sometimes wrongly assume it can be swapped for का (kaa) or की (kii) inside those fixed expressions -- it cannot.

Sense 2 : compound-postposition base ('to', 'for', 'like', etc., inside fixed frames)
postposition Functions as the connecting piece in a large family of compound postpositions -- के लिए (ke lie, 'for'), के पास (ke paas, 'near/has'), के बाद (ke baad, 'after'), के सामने (ke saamne, 'in front of'), के बिना (ke binaa, 'without') -- where के (ke) itself contributes no separate meaning but glues the noun to the second element.
Frequency: high
Cultural Note: This is the same के (ke) as the possessive sense -- these compound postpositions are literally built as 'of + noun', e.g. के पास (ke paas) is historically 'in the vicinity of', which is why को-marked or possessive logic (जैसे मेरे पास है (mere paas hai, 'I have')) keeps surfacing in Hindi's way of expressing possession and location.
Common Mistakes: 1) Learners sometimes drop के (ke) and use only the second word (e.g. साथ (saath) alone instead of के साथ (ke saath)), which sounds incomplete or overly clipped in most contexts. 2) Mixing up which compound postpositions take के (ke) versus की (kii) (e.g. की तरफ़ (kii taraf) but के सामने (ke saamne)) is a common source of error, since it is not always predictable from meaning alone.
