What does the japanese word ッ (Tsu) mean in English?

it's a little tsu (tsu being the sound if it is not little - observe ツ compared to ッ), essentially a glotteral stop (or if you want to get really technical, it is a geminate consonant)

It has no meaning by itself.

It is used to indicate a slight pause in between two sounds in Japanese. For instance, if you say the word 'rock' (or how I say it anyway) you will find a pause between 'ro' and 'ck' (if you say it without the pause, it will sound more like 'rawk'). You probably wont hear it though, as in English we don't really need to use it to make a distinction between words that sound similar, and therefore don't mark it, and therefor don't hear it till we are trained to notice it.

In Japanese it can make the difference between words, for instance:

キタ kita, I came

キッタ kitta, I cut it

They sound slightly different, the latter having a slight pause (so to speak) between ki and ta

I wouldn't agree with bellie, that is shortens the vowel sound much at all (as you can say these things as slowly as you want really), it is more a lengthening of the gap between voicing one sound and voicing the next. Or more of a sudden stop

Tsu Katakana

In Japanese, it's a small katakana character used to shorten the previous character. Each hiragana and katakana character is a single syllable. For example using kanji, 八ッ場 (hachi jjō), the small ッ caused the jō to become pronounced as jjō. As for the meaning, I have no idea. I just grabbed a random example off of google.

Also, you should re-word your question. A Japanese word does not mean English. A Japanese word means in Japanese. It can be translated into an approximate English meaning. However, understanding isn't included. As most people stated, ッ is really just a particle used in Japanese sentence structure. Japanese isn't English encoded in a different way. Japanese is Japanese, French is French. 日本語は日本語。フランス語はフランス語。英語は？

I'm critical that way, so sue me.

japanese word tsu english

ッ has no meaning or sound but it can be used in written language to express strong emotions for example だめっ！(No!) or ダメッッッッッ！with little tsu at the end is(looks) stronger than just だめ！or ダメ ！ and ッused by itself as in 「・・・・・ッ！」 usually means the person is surprised, shocked, angery..etc.

--edit--

八ッ場 is a proper noun and is pronounced yanba or yatsuba (but this is an exception).

No, Belie is very correct.

ツ is a tsu

シ is a shi

ッ is a consonant doubler (maybe it has a real description, who knows..)

Size is everything. ?

But anyway, a ツ isn't a "word," it's a sound used to make words. In itself it means nothing.

1. That's not a word.

2. That's not pronounced as tsu. It has no pronunciation at all, its function is to repeat the following consonant or to shorten the sound.

チケット = chiketto the t of to is being reproduced

アッ = a!

I am wondering if tsu is related to tsuki ( a punch).

belie is right as much as i hate her she right if that sign was big then its pronounced as tsu it is small

ツ lonely dont have a meaning. if is lonely is used (in japanese) the same way we used the smiley =)

i case taht you mistaked ツ whit シ (SHI) that means the note B in music (pronunced shi) or (si)
