[Grammar] Is it possible to use ' a' before 'most'?

[marker]

Is it possible to say:

It's a most unforgettable thing in my life.
instead of:It's the most unforgettable thing in my life.

Is it in fact possible to use 'a' before 'most'? Any examples/exceptions?
Thanks for replies in advance.

There are 1,130 COCA citations for 'a most unusual + adjective'.

marker, if you see a followed by most, and then by an adjective, you can take it for granted that the most means very in such a case.

So it's possible to use 'a' before 'most' although it seems to be very rare.

a + most = very
the + most = most of all

Am I right?

It's not very rare when used to mean "very."

Welcome to a most joyous occasion.
It was a most beautiful day.
