ضَغْطَةٌ

The pressure of the grave; (S, Msb, K;) because it straitens the dead: (Msb:) its straitening. (Mgh.)

It is also explained by En-Nadr [ISh] as signifying مجاهرة [apparently a mistake for مُجَاهَدَةٌ, as meaning (assumed tropical:) The exertion of one's utmost power, ability, or endeavour, in contending with another: and in this sense it should perhaps be written ↓ ضُغْطَةٌ]. (TA.)

See also ضُغْطَةٌ, in two places.
