Lesson 2.3: Dakuten and Handakuten

When learning the building blocks of writing Japanese, another thing to keep in mind is 濁点《だくてん》「゛」(Can't read it?) & 半濁点《はんだくてん》「゜」, also known respectively as てんてん(dot dot) and まる (circle) in informal circles. When applied to k, s, t and h 平仮名《ひらがな》 or 片仮名《かたかな》, their respective sounds change-k becoming g, s becoming z, t becoming d and h becoming b(with the exception of じ and ぢ, which are both pronounced 'ji'). ゛ are also applied to the 片仮名 ウ to signify v sounds in the written language「ヴァ(va)/ヴィ(vi)/ヴ(vu)/ヴェ(ve)/ヴォ(vo), respectively」 

Allow me to present a sample chart of some of the various changes.

k-sounds:か(ka),き(ki),く(ku),け(ke),こ(ko)
Now let's apply 濁点 and watch the the sounds change to this:
g-sounds:が(ga),ぎ(gi),ぐ(gu),げ(ge),ご(go)

With the above exceptions, the rest of the applicable 平仮名 follow the same pattern of addition and change in sound. For all the uses ゛ has, though,゜ only has one known one with the h family of 仮名, changing them from h to p sounds. Kinda strange, but at least it's only one more thing to learn with it, and less is always more, with how much you gotta learn.
