This is a Closed Compound Word ( A single non hyphenated or non seperated word made of 2 seperate words).

Made up of 2 words say A and B

When reversed it is also a closed compound word. So both AB and BA are
closed compound words.

The word AB results from the word BA

It has 5 consonants.

Words only from a standard Webster or Oxford dictionaries please. No proper nouns or slang words.

It is a simple word so please do not go to computers and check all compound words!

There may be 2 solutions. Second one a little stretched.

Hint

It fills the blanks in the following

That ________ must have come from a _______.

For the second solution

They make them do a lot of ________ in that ________.

Here's a simple 5-consonant possibility...

When you're having a sleepover, you might oversleep. Hence one results in the other.

A couple more to match that new template:

That gunshot must have come from a shotgun.


That houseguest must have come from a guesthouse.

And for that second template, maybe:

They make them do a lot of housework in that workhouse?

Other words I could think of that don't quite fit:

An upstart could come from a startup company, but I think the correct form is start-up.


There's also overturn and turnover, but they're too much alike.


A birdsong comes out of a songbird, but it has 6 consonants.


And a houseboat could come out of a boathouse, I guess, but it has just 4 consonants. Though you could always cheat a little and pluralize it. ;)

I found three solutions:

BEATDOWN/DOWNBEAT, OVERHANG/HANGOVER, OVERPASS/PASSOVER.

Besides having fewer than 5 consonants, I thought of a palindromic compound word almost immediately:

racecar

Writeover /overwrite

Comeover /overcome

night over/overnight
