Mornin' all.
"He works with hard scores in some orchestras" = maestro.
"Tussle with wild steer, introducing lasso at first" = wrestle. So the steer is 'wild', we introduce the L - where does the W come from?
"Study of shy bats in campsite abroad" = metaphysics. The root clue seems inadequate here (study of) or am I missing something?
"Player notices husband overcoming resistance" = sportsman.
Many thanks.
