Phrasal Verbs: An Introduction

The particle changes the meaning completely, not just slightly

Tamil doesn't build new verb meanings by tacking a small directional word onto an existing verb this way — give and up combine to mean 'quit', a meaning you can't derive from either word alone. This is one of the most distinctly English features on this whole course, with no Tamil shortcut to reach for. The only real strategy is to learn each phrasal verb as its own vocabulary item, exactly like memorizing an idiom, rather than trying to calculate its meaning from the parts.
