Guessing gender from the ending

The trick

Most Hindi nouns ending in the आaasound are masculine. Most ending in ईeeare feminine. That single rule gets you most of the way, and the exceptions are a short list worth learning by heart.

Worked example

1. 1Ends in ाaa→ usually masculine: लड़काladakaa, कमराkamaraa, रास्ताraastaa
2. 2Ends in ीee→ usually feminine: लड़कीladakee, रोटीrotee, नदीnadee
3. 3Ends in नाnaa(verbal noun) → masculine: खानाkhaanaa, पढ़नाpadhanaa
4. 4Ends in ताtaa/ तीtee(quality) → feminine: सुंदरताsundarataa, मित्रताmitrataa

So: Masculine — it ends in आaa
