Como para
 

Hi everyone

According to Google, the following two sentences both translated as "I'm too tired to chat."

- Estoy demasiado cansado como para charlar.
- Estoy demasiado cansado para charlar.

Is there a nuance that "como" adds that gets lost in translation, or do both sentences mean essentially the same thing?


Thanks

Think of 'como para' as introducing a phrase that states the expected or possible outcome of what was stated previous (the comparison). (The phrase "Tan grande como yo" is a comparison, but has no 'possible/expected outcome' phrase included. When you need to state the consequence, another phrase is needed and this is introduced with 'para'.)
Think of 'para', without 'como', as stating a purpose.

If you can't see a difference in meaning when translation occurred, the consequence (possible or expected outcome) was lost on the translator (be that a person or a machine).

That's the way I see it.

Does changing "como para" for "para" change the understanding of the sentences in the example? I.e. in both, the speaker is too tired for chatting.

There is no change of meaning. Both, "como para" and "para" are used interchangeably in these cases.

Cheers. Thanks
