in a nutshell

adv

Etymology: Calque of New Latin in nuce, derived from an anecdote in Pliny the Elder, who ascribes to Cicero the claim that the whole Iliad was once written on parchment and enclosed within a nutshell (Naturalis Historia 7.21.85). Compare typologically Czech stručný, stručně (< struk).

1. In summary; briefly or simply.

   “He had a lot to say, but his answer, in a nutshell, was no.”

   “Sadio Mané wasted a glorious chance in the first half and, late on, Mohamed Salah turned his shot against a post after a goal-line clearance had spun his way. That, in a nutshell, perhaps sums up the difference between Messi and the players on the next rung below – the ones who can be described as great footballers without necessarily being football greats.”
