Es solo una suposición, no tengo pruebas todavía.

It is just an assumption; I don't have proof yet.

Tu suposición sobre el clima fue correcta.

Your guess about the weather was correct.

Partimos de la suposición de que todos están de acuerdo.

We are starting from the assumption that everyone agrees.

Words that end in '-ción' are almost always feminine. You should always use 'la' or 'una' with this word (la suposición).

Mistake: "Using 'suposición' to mean 'supposedly'."

Correction: Use 'supuestamente' for 'supposedly'. Use 'suposición' only when you are talking about the noun (the idea itself).

When you want to say 'I'm assuming...', instead of using the noun, Spanish speakers often use the verb 'suponer' (Supongo que...).
