i-adjectives: the sa-form

The Japanese language is very flexible with adjectives. The sa-form allows to use an i-adjective as a noun or in other words to add ~ness to it (e.g. useful => usefulness, powerful => powerfulness, etc.)

It is very easy to build. Just replace “i” at the end of the word with a “sa”. So 楽しい (tanoshii, enjoyable) becomes joy as 楽しさ (tanoshisa). Here are a few more examples to make it clear.

Plain Form Romaji Meaning sa Form Romaji Meaning
楽し tanoshii enjoyable 楽し tanoshisa joy
美し utsukushii beautiful 美し utsukushisa beauty
新し atarashii new 新し atarashisa newness
akai red akasa redness
大き ookii big 大き ookisa size, dimensions

Example sentences:


nihon no otera no utsukushisa ga suki desu.

I like the beauty of Japanese temples.
