Questions & Answers about אני פשוט רוצה לנוח בבית.
Sometimes it can be omitted in casual speech if the context is very clear, but אני is completely normal here. One important reason is that Hebrew present-tense forms like רוצה do not clearly show person the way many past-tense forms do. In ordinary spelling, רוצה can fit I, you, or he/she, depending on context and pronunciation.
So adding אני makes it clearly mean I just want...
Here פשוט means just, simply, or all I want is...
It often gives the sentence a softer, more natural tone, as if the speaker is saying nothing complicated — I only want to rest at home. If you remove פשוט, the sentence is still grammatical, but it sounds a bit more plain and direct.
Yes. רוצה is the normal present-tense form used to say want / wants in Modern Hebrew. So אני רוצה is simply I want.
Hebrew does not need a separate helper word like English do, and it does not say something like I am wanting here. The ordinary way to express this is just אני רוצה.
