Usually, my thoughts of the day are profound thoughts built on movie dialogues and passages from books. Very often tongue-in-cheek humor. But sometimes we need to go to basics. What is the meaning of spar? According to many dictionaries and I am using the FreeDictionary.
How do I know sparring? We do it very often in my Shotokan Karate Dojo - the key is absence of violence. Boxers train by sparring for real fights so that do not get hurt. Oh, English language. Oh, Shakespeare.
Another meaning is also used for gamecocks - that has a hilarious meaning of some significance. Oh, sparring. Oh, gamecock.
Note: Any resemblance to anything real is purely coincidental and unintentional. I just sometimes teach myself English.
