Matching the person
This word is a describing word, so it must match the gender and number of the person it describes. Use 'sediento' for a man, 'sedienta' for a woman, and add an 's' for plurals.
Using 'Estar'
Because being thirsty is a temporary state, you should use this word with the verb 'estar' (to be) rather than 'ser'.
Using 'Soy' instead of 'Estoy'
Mistake: “Soy sediento.”
Correction: Estoy sediento. Use 'estar' because you aren't a thirsty person by nature; you just feel that way right now.
