"When did I tell a lie?"

Translation: Quando eu contei uma mentira?

[DominoD87]

'disse' can be used instead of contei?

[rakkenshi0]

You need the verb "contar" in this sentence because you say "contar uma mentira" for "to tell a lie". You also use "contar" in "contar uma história (to tell/narrate a story)", but you can't say "dizer uma história".

[Pedro_Santiago_]

So if we use "disse" in this sentence is wrong, isn't it?

[davtoh]

I did use disse and was counted as right.

[MariaSilfverberg]

Is it that dizer is say and contar is tell (something)?

[Fallacy79]

I try to think of 'contar' as 'to recount'. As in, 'to recount a story'. This helps me remember when to use 'contar' or 'dizer'.

Great tip.
