soportar vs apoyar
'Support' splits in two. Soportar is to bear or put up with. Apoyar is to back someone or lean something on a surface.
soportar
To bear, endure, stand — or to hold up a weight structurally.
No soporto el calor.
I can't stand the heat.
Toleration of something unpleasant. Almost always in the negative.
No lo soporto.
I can't stand him.
Strong dislike of a person. Stronger than 'no me gusta'.
Estas vigas soportan todo el techo.
These beams support the whole roof.
Structural support — physical load.
apoyar
To back someone emotionally or politically, or to lean or rest something on a surface.
Te apoyo en lo que decidas.
I support you whatever you decide.
Moral or practical backing. The everyday 'support' for people.
Apoyó la bici contra la pared.
He leaned the bike against the wall.
Physical resting. Apoyarse = to lean on.
Muchos votantes apoyan la propuesta.
Many voters support the proposal.
Political backing.
Tricky bit
'Te soporto' means 'I put up with you' — not at all 'I support you'. Learners who want to be kind and say 'te soporto' give offence. Use 'te apoyo'.
