In our last lesson, we discussed the expression on se croirait (literally, "one would believe oneself"), which means "it feels like." Now we'll take a look at a similar expression: on dirait. Both are impersonal expressions using a verb in the conditional. On dirait literally means "one would say," but it's also a synonym of il semble (it seems/looks like).
When introducing a clause, on dirait is followed by que:
On dirait que les gens sortent de la terre
It looks like people are coming out of the ground

But when it comes before a standalone noun ("it looks like x"), you don't need the que:
On dirait un serpent à pattes.
It looks like a serpent with paws.Play Caption
You can also use on dirait by itself, without introducing a noun or clause:
C'est ton jour de chance, on dirait.
It's your lucky day, it seems.

Je suis rouge de colère.
I'm red with anger.
On dirait pas.
It doesn't look like it.

Depending on context, on dirait can mean something more specific than "it seems/looks like":
On dirait que t'as huit ans
You act like an eight year old

On dirait... on dirait Cluzet!
It sounds... it sounds like Cluzet [French actor]!Play Caption
And sometimes it comes closer to its literal meaning:
Belle, c'est un mot qu'on dirait inventé pour elle...
Beauty, it's a word you could say was invented for her...
[Beauty, it's a word that seems to have been invented for her...]Play Caption
But be careful: dire is a very common verb, so you'll just as often encounter on dirait used in a literal sense.
On dirait pas "as-tu", axe verbe en premier, sujet en deuxième...
We wouldn't say "have you," verb in first position, subject in second...
