The word ‘guess’ in Spanish can be translated as ‘adivinar.’ This verb is commonly used when you want someone to make a conjecture or an estimation about something. For instance, if you are playing a guessing game, you might say, ‘Adivina qué tengo en la mano,’ which means ‘Guess what I have in my hand.’
There are other ways to convey a similar idea in Spanish depending on the context. For example, if you are referring to making a guess in terms of an assumption, you might also use the phrase ‘suponer,’ which means ‘to suppose’ or ‘to assume.’
In summary, ‘adivinar’ is the primary translation of ‘guess,’ but remember to consider the context to choose the most appropriate term!
