Abstract Use

When 'seso' means 'judgment,' it is often used in the singular, unless you are using the specific idiom 'devanarse los sesos'.

Correction: In Spanish, to call someone the 'brains' of an operation, use 'cerebro': 'Él es el cerebro del grupo.'

Fundamento vs. Seso

Learners often confuse 'fundamento' and 'seso' by using 'fundamento' when they mean practical, quick judgment. Remember, 'fundamento' implies a lack of deeper maturity or seriousness, while 'seso' is about acting prudently and thoughtfully in the moment.
