You moron, the same word can have different meanings in different circumstances.
No it can't it can coney a meaning.
Let's explain it to a retars like you with examples.
I have sufficient food. (The necessary amount)
I have enough food. (The same as sufficient)
I have plenty of food. (More than enough)
I have an ample amount of food. (A lot more than enough)
I have an abundance of food. ( too much more than ample)
The only thing all 5 convey is the bare minimum past that they convey the excess.
Now I know you don't understand language but try to comprehend. Like I told you synonyms share an aspect they agree upon and convey their meaning within the confines of the word. They also convey other meanings with other words.
The purpose of synonyms is for variety of conveyance otherwise they'd be useless in and of themselves.
As for bequeach( a voluntary act done by the individual) it can never apply to genetic inheritance that's why you'll never find any grammarian or scientist or any human say I bequeached by genes to him. Or I bequeached my blue eyes to him.
