unnoticing
Failing to see
Unnoticing describes someone who fails to observe or pay attention—the opposite of noticing.
It suggests a passive obliviousness rather than deliberate ignorance: She walked past him, unnoticing, lost in thought.
The word is uncommon, with *unobservant* or *oblivious* more frequently used.
