The Kanji 基本組手 mean Kihon Kumite.
基本 is often translated as basic and 組手 as fight, but also as meeting hands. If you take it a step further and look at the Kanji individually you might come to the following logic translation: (I especially say 'logic', because 本 also means 'book' which will not help you in this case.
基: Basic, origin, source, cause.
本: Original, real.
組: Associate, construct, assemble, grapple.
You could conclude that Kihon Kumite is a fysical training to gain more knowledge and skill of the foundation of interaction between people.
Kihon gumite is a method to teach the basic elements of the interaction between you and your opponent. It teaches the principles of movement and taking control over your body when interacting with an opponent.
The Urawaza, Kumite no Ura or kumite gata -several different names are used for the same kind of techniques- teach the principles of movement and the principles of controlling the body of the opponent. It is like first learning how to talk, read and write and then eventually being able to write an essay, discuss matters, debate etcetera. Wado really is an educational system in order to finally harmonise with the laws of nature.
