"Matěj má raději čaj."

Translation: Matěj prefers tea.

[LeinadSpoon]

Food lesson 8 claims to teach the word raději, but I just redid it and it did not include that word at all...

[e.m.anderson1991]

It came up a little for me, but not in the context of "prefers." The translations kept coming up "likes" for the use of "have"+this word, but when I said "Matej likes tea" just now it was marked wrong because he <prefers> tea.

Raději is the comparative of rad, similar to radši

If you "mám rad", then you like something; if you "mám radši/raději", you like something more than other things, in other words; you prefer it.

(And if you like something the most, you add the superlative prefix "nej-" in addition to the comparative suffix "-ěji" -> nejraději.

Why don't you use the accent is "rád(a)"?

[ZangarZhanabek]

Why not "loves"?

[VladaFu]

"má raději" is the comparative of "má rád", that means "loves more", "prefers", not just loves. See also the oexplanation by bbrukernavn.
