expression, adverb, noun which may take the genitive case particle 'no'
on a routine basis; regularly; habitually
Emphasizes that something is done as a matter of course in one's daily life, not just occasionally. Often used when contrasting with a special or one-time action.
普段から運動している人は、体力がある。
People who exercise regularly have good stamina.
普段からよく寝るようにしている。
I make a point of getting enough sleep on a regular basis.
Compound of 普段 (ふだん, 'usual, ordinary') + から (particle meaning 'from'). The phrase literally means 'from one's usual state' and developed into an adverbial expression for habitual actions.
