All your examples, 入る[hairu], 限る[kagiru], しゃべる[shaberu], are GODAN verbs. All "iru/eru" ending verbs are NOT ALWAYS ichidan verbs. For instance, "kiru" as "to wear" is an ichidan verb, whereas "kiru" as "to cut" is a godan verb.
着る[kiru] "to wear" (ichidan) --> kinai, kimasu, kirareru(potential/passive/honorific)
切る[kiru] "to cut" (godan) --> kiranai, kirimasu, kireru(potential), kirareru(passive/honorific)
As for "tabereru", that is so-called "ra-nuki kotoba", a conjugation which is widely used colloquially but unaccepted officially.
The example 2 お父さんは新聞を読まれました is usually interpreted as an honorific. If it's the passive, that's aindirect passive/passive of adversity. An article that is not good for dad is on the newspaper, and someone read it.
"The newspaper was read (by Dad)." is お父さんに新聞を読まれました. This is also an indirect passive. The newspaper is MY newspaper or the newspaper that has an article not good for ME was read by Dad.
Are there any typos in #3 一昨日、田中村長は村で来られましたんだよ?
No, 食べていた/いました is the past progressive "was/were eating".Also, could passive for 'taberu' also be 'tabete ita/imashita'?
Unlike に/へ, まで indicates boundary/arrival point rather than direction. It sometimes also has a nuance of "even".Also, I've seen 'made' in reference to direction a lot recently, for instance in the sentence 'we'll push it to the top of the hill', the direction particle was made instead of ni or e. Is there a trick to knowing when to use made?
No. 来られましたよ/来られたんですよ is correct, as I wrote, but neither 来られましたんですよ nor 来られましたんだよ are grammatically incorrect. The explanatory ん can't be attached to the polite form ます/ました.Koraremashita yo and koraremashita n desu yo both work, is 'nda' then basically off-limits or false?
Ahh, so passive would be 'was read' whereas past progressive would be 'was reading'? I have a very limited knowledge of the terms that are connected to these verb forms, so forgive my slowness in the area.No, 食べていた/いました is the past progressive "was/were eating".
That makes sense! Thank you very much!Unlike に/へ, まで indicates boundary/arrival point rather than direction. It sometimes also has a nuance of "even".
This makes sense, so I only have to remember that the explanatory ん must not go after masu/mashita?No. 来られましたよ/来られたんですよ is correct, as I wrote, but neither 来られましたんですよ nor 来られましたんだよ are grammatically incorrect. The explanatory ん can't be attached to the polite form ます/ました.
