In my studying Haiku I have come across a few interesting tidbits and decided to post them here. I will post one every week. I hope you glean something from these tips.
1. The plural of Haiku is Haiku NOT Haikus.
Why? Well, many Japanese words have no plural (like the english words sheep or deer) so there is no (s) added. It is therefore grammatically incorrect to do so.
