How to say "software" in Japanese

Choosing the right word

ソフトウェアCommon
nounThe full loanword for computer software — the programs a computer runs. It suits technical writing and product descriptions as well as everyday conversation, and is the word to reach for in most contexts.
彼かれらはソフトウエア製品せいひんを扱あつかっている。↗
They deal in software products.
ソフトJLPT N4approx.Common
nounA short form of ソフトウェア with the same meaning. In everyday conversation about computers — installing a new program, say — people often use ソフト rather than the longer word.
その子こはプレイステーションの新あたらしいソフトが欲ほしいとだだをこねた。↗
When the kid wanted the latest PlayStation software, he acted like a spoiled child.
ウェアCommon
noun (suffix)Really just the '-ware' element found at the end of longer loanwords, as in ソフトウェア itself. On its own it is seldom the word you want for 'software'; use ソフトウェア instead.

For computer software, 「ソフトウェア」 is the full, neutral word; 「ソフト」 is its everyday short form with the same meaning; 「ウェア」 is merely the '-ware' element and seldom works alone.
