This is the 1345th most frequent Russian word.
хочу
"Хочу" means "I want."
The word 'хочу' is used here to express a personal desire or need for an action, 'пить' (to drink).
Я хочу пить.
I want to drink.
Although 'хочу' is conjugated as 'хотят' for the plural subject 'дети,' it maintains its root meaning of 'wanting' an action or activity, 'играть' (to play).
Дети хотят играть в парке.
The children want to play in the park.
Here, 'хочу' in its conjugated form 'хотят' conveys the desire of the plural subject 'туристы' to perform a specific action, 'увидеть' (to see).
