Student or Learner
My question is for the phrase structure "on + (adjective) basis" such as "on regular basis", "on daily basis" ... etc, must I use the article "a" before the adjective such as "on a regular basis", "on a daily basis" ... etc or could I simply omit the article "a"?
Thanks in advance!
You need to use the indefinite article.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
