अजनबी (ajanbii)

noun/adjective A single core meaning: 'stranger, unfamiliar person,' used as both a noun and an adjective describing someone (or something) unknown.
Sense 1 : a stranger, an unknown person
noun, masculine
Synonyms: अनजान व्यक्ति (anjaan vyakti, phrase, unfamiliar person), गैर (gair, outsider/not one's own)
Frequency: high
Cultural Note: अजनबी (ajanbii) carries a slightly literary, wistful flavor -- it shows up constantly in film song lyrics and ghazals about chance encounters and lost connections, more evocative than the flatter अनजान व्यक्ति (anjaan vyakti). In everyday Delhi speech you will hear it in warnings like अजनबियों से सावधान रहो (ajanbiyon se saavdhaan raho, 'be careful of strangers'), a common parental caution.
Common Mistakes: 1) Learners often reach for अनजान (anjaan) to mean 'stranger' as a noun, but अनजान (anjaan) is really an adjective ('unknown, unfamiliar') describing a person or thing -- अजनबी (ajanbii) is the go-to noun for 'a stranger' standing alone, as in किसी अजनबी से बात मत करो (kisii ajanbii se baat mat karo, 'don't talk to any stranger'). 2) The gender is fixed masculine in form regardless of who is referred to; it does not take a feminine ending, so आप एक अजनबी हैं (aap ek ajanbii hain) works for a woman too, though many speakers will also just say अजनबी औरत (ajanbii aurat, 'stranger woman') keeping अजनबी (ajanbii) invariant before the noun.
Sample Sentences:

Sense 2 : strange, unfamiliar
adjective
Synonyms: अनजान (anjaan), अपरिचित (aprichit, formal)
Frequency: medium
Cultural Note: Used adjectivally, अजनबी (ajanbii) often describes places or feelings as much as people -- यह शहर मुझे अजनबी लगता है (yah shahar mujhe ajanbii lagtaa hai, 'this city feels unfamiliar to me') is a very natural way to express homesickness or disorientation, leaning on the दिमाग/मन-को-लगना (dimaag/man-ko-lagnaa) 'feels to me' construction rather than an English-style 'I feel.'
Common Mistakes: 1) Being an invariant loanword adjective, अजनबी (ajanbii) never changes for gender or number, unlike native adjectives ending in आ (aa) -- अजनबी शहर (ajanbii shahar, 'unfamiliar city') and अजनबी जगह (ajanbii jagah, 'unfamiliar place') both use the same unchanged form.
