too / enough / so / such

A2 too / enough / so / such 31 / 50

En resumen

Usa too para «más de lo que quieres» (un problema), enough para «la cantidad justa» (bien), y so / such para reforzar un adjetivo o un sustantivo. Recuerda: too no es lo mismo que very.

La regla

too = más de lo necesario o de lo deseado. Siempre suena a problema.

too + adjetivo/adverbio: It’s too hot. / You drive too fast.
too much + sustantivo incontable: too much salt, too much noise
too many + sustantivo contable: too many people, too many emails

enough = lo justo que necesitas (neutro o positivo).

adjetivo/adverbio + enough (enough va DESPUÉS): old enough, fast enough, good enough
enough + sustantivo (enough va ANTES): enough money, enough time, enough chairs

too / (not) enough + infinitivo con to para dar un resultado:

too tired to walk (= no puedo caminar, es demasiado)
old enough to drive (= suficiente edad, está bien)
not warm enough to swim (= no hay suficiente calor)

Cuando quien hace la acción es otra persona, nómbrala con for antes de to: too heavy for my sister to lift / not warm enough for the children to swim.

so + adjetivo/adverbio lo refuerza: so tired, so quickly. such + (a/an) + (adjetivo) + sustantivo hace lo mismo con un sustantivo: such a long day, such nice people. Las dos suelen añadir una oración con that para mostrar el resultado: so tired that I slept / such a good film that I saw it twice.

too frente a very: very good = simplemente fuerte (positivo). too good = un problema. No digas «The film was too good, I loved it» — usa very.
