"I didn't do it *on* purpose" in spanish

Question

So... I would say, after checking a little bit:

"No lo hice a propósito"

But I would LIKE to say either: "...en propósito." "...con propósito" "...de propósito" Does anyone of these also make sense?

---

Also: if none of them makes sense, is "do it ON" always translated with "hago A"? As in, for example: "Do it on demand" or "Do it on schedule"

Why not make a stab at popularizing "toward purpose", "for purpose", "under purpose", usw in English? - EugenioCosta, May 28, 2013

Answer 1

But I would LIKE to say either: "...en propósito." "...con propósito" "...de propósito" Does anyone of these also make sense?

No, they don´t. ...... a propósito is the only correct way.

Hazlo por demanda / a petición.

Hazlo a tiempo.

Prepositions are not normally mix-and-match. They have their own corresponding words, so memorization is necessary.

Answer 2

A propósito is a set phrase so I'm afraid you can't swap the prepositions around. Also using 'a' for 'on' won't always work - on demand is usually 'por encargo' although I guess you could use 'a pedido'.

Answer 4

I hear this more often to mean the same thing, "Lo hice sin culpa". I did it without fault. More or les "I did it but it's not my fault"

Answer 6

Usually, "en propósito, con propósito, de propósito" don't make sense
