  Usage
  Slow is normally used as an adjective (a slow learner). It is also used as an adverb in certain contexts, including compounds such as slow-acting and in the expression go slow. Other adverbial use (e.g. he drives too slow) is informal and non-standard and in such contexts slowly should be used instead.
