Deep

[a feeling of deep satisfaction over the outcome of something]

A concentrated implementation of technological innovations typically will not get under way before the global economy has gone through a deep crisis

Accept my deep sympathy

And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters

between the devil and the deep blue sea

deep

deep dark secret

deep in debt

deep into the night

Draw a deep breath!

He is in deep doo-doo

He is swimming in deep waters

He’s a deep me

He’s already deep in debt to her
