The Spanish word 'tirada' comes from the verb 'tirar' meaning 'to throw' or 'to pull', combined with the suffix '-ada' which forms action nouns. The verb 'tirar' itself can be traced back to Vulgar Latin 'tirare' meaning 'to shoot (an arrow)', which ultimately derives from the Parthian word 'tir' meaning 'arrow'. This shows how the meaning evolved from a specific action with arrows to a more general concept of throwing or pulling.

The most common related Spanish word is the verb 'tirar', which is simpler and more frequently used. While 'tirar' is the action of throwing or pulling, 'tirada' refers to the act or instance of throwing/pulling. You might also encounter words like 'tiro' (a shot or throw) and 'tirón' (a pull or tug), which are part of the same word family.

While English doesn't have any direct cognates from the Parthian 'tir', the word 'tier' (as in 'tears/tiers of something') is sometimes confused with this root. However, they are not actually related - this is just a false friend. The concept of 'throwing' or 'pulling' in English comes from different Germanic roots.
