"an objection that is immaterial after the fact"
"an incorporeal spirit"
"ghosts and other immaterial entities"
"an issue extraneous to the debate"
"the price was immaterial"
"mentioned several impertinent facts before finally coming to the point"
"whether you choose to do it or not is a matter that is quite immaterial (or indifferent)"
"what others think is altogether indifferent to him"
We sensed a strange intensity in the air, something immaterial.
