(T, TA.) ― -b3- تَأْلِيفٌ is The putting many things into such a state that one name becomes applicable to them, whether there be to some of the parts a relation to others by precedence and sequence, or not: so that it is a more general term than تَرْتِيبٌ: (KT:) or the collecting together, or putting together, suitable things; from الالفة [i. e. الأُلْفَةُ]; and is a more particular term than تَرْكِيبٌ, which is the putting together things, whether suitable or not, or placed in order or not.
