Questions & Answers about Tienes que verlo porque su esfuerzo es incansable.
How does the word incansable break down, and can I use this pattern for other words?
Incansable comes from the verb cansar (to tire). Adding -able makes it an adjective meaning 'capable of being tired,' and the prefix in- makes it negative: 'incapable of being tired' or 'tireless.' You will see this same pattern in words like innegable (undeniable, from negar) or inolvidable (unforgettable, from olvidar).
The translation says 'his effort,' but couldn't su esfuerzo also mean 'her effort' or 'their effort'?
Yes. The possessive adjective su can mean his, her, its, their, or your (formal). Without surrounding context, this sentence could equally mean 'her effort' or 'their effort.' If you need to clarify who it belongs to in a real conversation, you could say el esfuerzo de él.
Could I put the lo before the verb phrase, like lo tienes que ver?
Exactly. When you have a conjugated verb followed by an infinitive (like tienes que ver), the direct object pronoun can either attach to the end of the infinitive (tienes que verlo) or go before the conjugated verb (lo tienes que ver). Both are perfectly natural and mean the exact same thing.
Why use tienes que instead of debes here?
Tener que expresses a strong, objective necessity or obligation, much like 'have to' in English. Deber is often softer, closer to 'must' or 'should,' expressing a moral obligation or strong recommendation. Here, the speaker is expressing strong enthusiasm or necessity ('You have to see it!'), making tienes que the most natural fit.
