Last week I had an year-end party with themy English study group in my town last weekmember in the town I live.

Around 20 people attended, including six English teachers attended.

MORE SUCCINCTLY: I sat next to a teacher who is from Australia, so I cancould speak English a lot.

We talked about zodiac signs and personalities.

She said she can beI would describe her as feisty.

I've leant the word "feisty" before, but I wanted to make sure theits meaning, and I asked "what anime characters do you think ofare feisty?"

She doesn't watch anime, so she wasn't sure what character is feisty, but another teacher answered "maybe, Katsuki Bakugo from My Hero Academia?"

I thought maybe I understand.

Year-end Party (108)End of Year Party

I had an end-of-year-end party with the English study group in my town last week.

Really good grammar order here (I had X with the X in my town last week)!

Around 20 people, including six English teachers, attended.

"attended" is a really good word choice.

If I am being extra-picky, we might not use "attended" for something like a party. Instead, we might say "came along" or "turned up".

"Attend" is a more formal word.. we "track attendance" at school, or we use it for things like work meetings.

We rented ouserved a section at an Italian restaurant for the party.¶

Your sentence ("rented out") suggests you booked the entire restaurant (i.e. no other customers were allowed to come to the restaurant).

I sat next to a teacher who is from Australia so I canould speak English a lot.a lot of English.

We talked about zodiac signs and personalities.

I've lheantrd the word "feisty" before, but I wanted to make sure the meaning, andI fully understood what it meant, so I asked "what anime character do you think ofwould you describe as feisty?"

She doesn't watch anime, so she wasn't sure what character is feistyable to think of a character, but another teacher answered "maybe, Katsuki Bakugo from My Hero Academia?"

I thought maybe I understandfelt that I understood... maybe.

→ I felt 80% sure that I understood.

→ I think I got it, but I'm not absolutely certain.

Ps...there's no direct translation of "feisty" into Japanese, so my Japanese version is one of one of translations.my best guess/attempt.

"I sat next to a teacher who is from Australia" is correct, but "I sat next to a teacher from Australia" is less formal and the most natural way to describe where the teacher is from.

I've leantrned the word "feisty" before, but I wanted to make sure I understood the meaning, andso I asked, "wWhat anime character do you think ofis feisty?"

She doesn't watch anime, so she wasn't sure what character is feisty, but another teacher answered, "mMaybe, Katsuki Bakugo from My Hero Academia?"

I thought maybe I understanood.

In English, both "think" and "understand" have to be in the past tense when you say "I thought...". An exception is when are quoting yourself (using quotation marks).

For example, this is correct:

I thought, "Ah, I understand!".

PsS... there's no direct translation of "feisty" into Japanese, so my Japanese version is one of one ofmany translations.

I've learnt the word "feisty" before, but I wanted to make sure of the meaning, and I asked, "wWhat anime character do you think ofis feisty?"

She doesn't watch anime, so she wasn't sure what character is feisty, but another teacher answered, "mMaybe, Katsuki Bakugo from My Hero Academia?"

"An" is for words that start with vowels in the phonetic sense, and year does not

Around 20 people, including six English teachers, attended.

This reads more naturally with pauses/commas around the subclause

We talked about zodiac signs and personalities.

I've leant the word "feisty" before, but I wanted to make sure I understood the meaning, andso I asked "what anime character do you think of as feisty?"

To make sure X, is to make it certain X happens. X has to be an action, so I inserted an action here

Using "so" instead of "and" is better here as the final clause is because of the middle clause.

She doesn't watch anime, so she wasn't sure whatich character is feisty, but another teacher answered "maybe, Katsuki Bakugo from My Hero Academia?"

People will absolutely say "what character" here, but it's not considered correct so should be avoided in writing.
