We saw AN otter.
You use ‘an’ when the next word starts with a vowel.
For example:
With vowel - There was AN eagle.
Not a vowel - There was A bird.
I think the third one down. I had to sound out the words, though.
I'm pretty sure it is Theme.
Theme is the central topic of the text. passage, story, or anything else. So it may possibly also be the same for the underlying meaning and universal truth...but again, I am not sure.
