が欲(ほ)しいTo want something, To be in need of

がほしい and がる both express desire but differ in usage. がほしい straightforwardly expresses the speaker's own wants, e.g. 車がほしい ('I want a car.'). In contrast, がる attaches to adjectives (e.g. ほしい becomes ほしがる) to describe what someone else appears to feel, e.g. 田中さんは車をほしがっている ('Mr. Tanaka seems to want a car.').

がほしい and たがる both express desire but differ in usage. がほしい is used for the speaker's own wants, e.g. 車がほしい ('I want a car.'). たがる combines the たい-form of verbs with がる to describe a third person's apparent desire to do something, e.g. 田中さんは車を買いたがっている ('Tanaka seems to want to buy a car.').

Both がほしい and てほしい express a want, but differ in meaning and usage. がほしい follows nouns to express the speaker's desire for something, whether physical, e.g. 金がほしい ('I want money.') or figurative, e.g. 自由がほしい ('I want freedom.'). In contrast, てほしい uses the て form of a verb to express a desire for someone else to do something, e.g. これを見てほしい ('I want you to look at this.').

Both the たい form and がほしい express desires, similar to the English 'want.' The difference is that たい is used with verbs to express one's desire to perform some action, while がほしい is used after nouns to express one's desire for an object. For example, 日本に行きたい means 'I want to go to Japan' (desire to do something), while お金がほしい means 'I want money' (desire for an object).

These two patterns using ほしい to express a 'want' differ in meaning and usage. がほしい follows nouns to express the speaker's desire for something, whether physical (金がほしい = 'I want money.') or figurative (自由がほしい = 'I want freedom.'). ようにしてほしい combines ようにする and てほしい to express a desire for someone to act in a certain way, e.g. 忘れないようにしてほしい ('I want you to make sure not to forget.').
