きちんとした性格の母さん Sentence help


I would like some help understanding this sentence.

あの真面目できちんとした性格の母さん（が動詞をする）

I don't understand the した性格 part, because how can した modify "personality"
which can't do anything?

I also don't understand the function of 真面目で, especially what the で particle
means.

If I had to give a translation, I would say: Given her real personality, my
mother ....




> I don't understand the した性格 part, because how can した modify "personality"
> which can't >do anything?

きちんと on it's own is an adverb, for example きちんと掃除をする/do the cleaning
_properly_.

It's one of those words you can add する to afterwards to make it into an
adjective. For example: 母さんは性格がきちんとしている / (My) mother has a
proper/orderly/impeccable personality.

This gets put in the past tense* when it is brought in front to modify the
noun (性格): きちんとした性格の母さん / (My) mother who has an proper personality.

> I also don't understand the function of 真面目で, especially what the で particle
> means.

Let's look at another sentence where it might be easier to understand:
真面目で誠実で優しい人/ a serious _and_ sincere _and_ kind person.

You connect na-adjectives together with で the same way you might connect
i-adjectives together with ～くて, for example: 安くておいしいケーキ/cheap and tasty cake.

So 真面目できちんとした性格の母さん here means: (My) mother who has a stiff and proper
personality.

*I swear there was a question about this and I wanted to link to it but I couldn't find it...
