Some quick related queries on use of pronoun objects with the lexical verb-noun in the past tense construction with "wnes i".
I'm currently on Challenge 20 of Level 1 (Northern), having never done any modern Welsh before. In the past couple of lessons I reckon I've heard both "Wnes i ei mwynhau" and "Wnes i ei fwynhau", and also "Wnes i wylio fo."
First question -- I understand that the difference between the forms with & without mutation is one of gender. Am I right in assuming that the idea is basically to get us used to hearing and saying both versions, before we tackle the whole issue of gender at some later point?
Second question -- I don't get why the pronoun object sometimes precedes, sometimes follows the verb-noun. Having only heard "ei fwynhau", the alternative "wnes i fwynhau fo" sounds... wrong to me -- but is it? On the other hand, "wnes i ei wylio" doesn't sound obviously dodgy to me -- but is it?
(Please assume I know a reasonable amount about languages and nothing about Welsh outside of the course content -- it's not quite true, but nearly so!)
Diolch yn fawr iawn!
