دِخَالٌ (JK, M, K) and
دَخِيلٌ; (K;) but this last is not in the M [nor in the JK], and requires consideration: (TA:) [perhaps the joints (مَفَاصِل) here mentioned are those of a coat of mail; for it is said immediately before in the JK that دِخَالٌ in coats of mail signifies firmness, or compactness, of make. Hence also,] تَدَاخُلُ
اللُّغَاتِ [The intermixture, or commixture, of dialects]. (Mz 17th نوع.) And تَدَاخُلُ الأُمُورِ (assumed tropical:) The dubiousness and confusedness of affairs; as also الأُمُورِ
