[A lock;] a thing by means of which a door is made fast, (S, * O, * Msb, K, *) not to be opened save with a key; (S and K voce مِزْلَاجٌ;) a thing that is closed and opened with a key; (Mgh;) plural أَغْلَاقٌ, (Sb, Msb, TA,) its only plural: (Sb, TA:) and
مِغْلَاقٌ is synonym therewith; (S, Mgh, O, Msb, K;) plural مَغَالِيقُ: (Msb:) so too is
مِغْلَقٌ: (Msb, TA:) and so

meaning خِتَامَ الأَغْلَاقِ, the phrase being inverted by him. (TA.)فَبِتْنَ بِجَانِبَىَّ مُصَرَّعَاتٍوَبِتُّ أَفُضُّ أَغْلَاقَ الخِتَامِ
2.
Also i. q.
رِتَاجٌ, meaning A great door: whence the phrase مَفَاتِيحُ أَغْلَاقِهَا, by which are meant [the keys of] the [great] doors thereof. (Mgh.)
