The word 'fain' is an old-fashioned word that means 'gladly' or 'eagerly'. It can be used in sentences like "I would fain go to the park today" which means "I would gladly go to the park today" or "He was fain to help me with my homework" which means "He was eager to help me with my homework". However, it is not commonly used in modern English, so it is best to use it only in formal or literary contexts.
