I can't decide if the nouns "birth" and "management" are abstract or concrete but I think they are concrete. I know that "birth" is countable but I'm not sure if "management" is or not. Can it be both - the act of managing - uncountable & abstract and - the management team - countable and concrete.
Can anyone squash my doubts?
definitions for the word birth:
1. the time when a baby comes out of its mother's body.
Have you seen a time? Have you tasted a time? Have you touched a time? Have you smelled one? Have you heard one? No. No. No... --> abstract
2. a child which is born --> see a child; hear a child... --> concrete
(The percentage of live births.)
'birth' has both concrete and abstract senses.
management: a set of individuals -- this is an abstract concept. You can see all the individuals of the management, but the management itself you can't see; can't hear...
Both nouns can be put into plural.
