Lanzar vs. tirar vs. arrojar

While all three Spanish verbs 'lanzar', 'tirar' and 'arrojar' could be translated into English as 'to throw', each word has its own particular nuance and use influences how it's interpreted in different contexts.

Lanzar

'Lanzar' is often used to imply the movement of 'launching' or 'projecting' something. It carries a connotation of strength and intention.

Tirar

'Tirar' is more commonly used to indicate dropping or discarding something rather than throwing with force or aim. It's often used in daily, informal speech.

Arrojar

'Arrojar' typically implies the action of throwing forth or propelling something with intent. It can also mean to cast off or discard, though it's less commonly used than 'lanzar'. Its usage is more frequent in formal or literary contexts.

(The man threw a stone into the river.)
