かたかな is the 2nd Japanese syllabary we’ll cover. It is setup & sounds JUST LIKE Hiragana, but it used to write foreign & “borrowed” words & names of non-Japanese people. Words like  テレビ (terebi - television) &  ニコラス (nikorasu - Nicholas) will always be written in Katakana.
(かたかな (katakana) itself is written in hiragana since it is a Japanese word :P)

Don’t forget that these are pronounced just like the A & Ka lines in hiragana.

ア イ ウ エ オ
a  i  u  e  o
カ  キ  ク  ケ コ
ka ki ku ke ko

Some Words using these kana:
アルファベット - Alphabet
arufabetto

コアラ - Koala
Koara

Hiragana has one more part to further complicate it, but still not adding any more new characters. What we’ll be talking about today is described in several different ways. I was taught Contracted sounds, but it can be called double consonant hiragana, or just double hiragana. Take the 1st entry in the chart below- きゃ (kya. ) You’ll notice that the や (ya) is smaller than the き (ki) this is what tells the reader that it’s a contracted sound.

きゃ Kya
きや Kiya
^ at first glance, they appear to be the same, but there are different meanings & pronunciations.
