Miswording*:
Strawberry is not a berry and peanut is not a nut.
True definition: By botanical definition of a berry, berry is a simple fleshy fruit having seeds produced from a single ovary. But I prefer a simpler definition, although it may not be technically exact; berry is a fruit containing more than a single seed.
So by definition, there are many berries, which we never consider as berries: orange, melon, watermelon, grape, tomato etc.
There are only few "true" berries: blueberry, cranberry, barberry and gooseberry.
However, other well known "berries": strawberry, blackberry and raspberry are not berries.
Nut is a hard-shelled fruit. Nuts usually contain a single seed, and occasionally two, and it ovary wall becomes very hard at maturity.
Many so called "nuts" that we know: peanuts, walnuts, pistachios, almonds, coconuts, Brazil nuts and cashews are not nuts.
However, chestnuts and hazel nuts are "true" nuts.
* Probably, there is no such a word, but who cares when fruits which are not berries have been named as berries and fruits which are not nuts have been named as nuts
