"The lunch pleases her."

Translation: Prandium ei placet.

[Elin.7-1]

Coincidence: ei in Wlesh means his/hers. The gender of the owner is distinguished by a) placing e (male) or hi (female) after the noun; and b) mutating (treiglad) the beginning of the word differently: his takes treiglad meddwl and hers takes treiglad llais.

Since Welsh is an older language than Latin, I wonder if this means the pronoun goes back to PIE?

What about "Prandium se placet"?

[JaJsemAdam]

First, it would be "sibi" (dative), not "se" (accusative); second, "se", "sibi" etc. is used when the subject is acting on itself, so "prandium sibi placet" would mean "the lunch pleases itself". It's just like in Italian, you say "gli/le piace", not "si piace"; or in Spanish, you say "le gusta", not "se gusta"

Duolingo corrected me previously when I used "ei placet" for "is pleasing to him" and gave "Eius placet" as a correction . So I gave "Prandium eius placet" "The lunch pleases her". I don't understand . Was I right the previous time and the correction incorrect , so I should have ignored that correction . Or is there a difference between "to him" versus "to her", or something else ?

[JaJsemAdam]

In the first case, correcting to "eius placet" was wrong, report it. And no, there is no difference between "to him" and "to her", both are "ei".

Interesting.
Spanish has the same "is pleasing to me" construction. But the Spanish word "to please" is "gustar" (Cognate, "gusto.")
Le gusta el almuerzo. (Literally, Lunch is pleasing to her.)

It is the same in all romance languages - French s'il tu plait - if it is pleasing to you (please) and Italian: me piace cena - dinner is pleasing to me. (I like dinner)
