Certainty vs. Supposition

Use 'supongo que...' to introduce something you think is true but aren't 100% sure about. It's the perfect Spanish equivalent of 'I guess that...' or 'I suppose that...'.

Expressing Guesses with 'que'

After 'supongo que', you almost always use a normal, statement-making verb form (what's technically called the 'indicative'). Think of it this way: you are stating what you suppose. For example, 'Supongo que **estás** cansado' (I suppose you **are** tired).

Which Verb Form Follows?

Just like in English, 'supongo' can make your sentences sound less direct and more polite. Instead of saying a flat 'No,' you could say 'Supongo que no' to soften the message.

A Softer Way to Speak

You can use 'Supongo' by itself as a short answer meaning 'I suppose' or 'I guess so.' For example: '¿Vendrá Ana?' — 'Supongo.'
