Space and Right?

ഇട means gap. By extension, it also means opportunity.
ഇടയുക means to interlock, mix-up and by extension, to fight. An extension is ഇടകേട് ( ഇടങ്ങേട്), meaning complication.
ഇടയൻ is a shepherd.
ഇടം means space.
ഇടത്‌ means left.

Why is space or gap associated with left?

(വലം ('right') seems to be related to വൽ- meaning 'big'. Compare to വലിയ. )
