One of the most difficult problems nearly ‘ all lexicographers face is recording the word-meanings and arranging them in the most rational way, in the order that is supposed to be of most help to those who will use the dictionary.
If one compares the general number of meanings of a word in different dictionaries even those of the same type, one will easily see that their number varies considerably.
Compare, for example, the number and choice of meanings in the entries for arrive taken from COD and WCD given below1. As we see, COD records only the meanings current at the present moment, whereas WCD also lists those that are now obsolete.
The number of meanings a word is given and their choice in this or that dictionary depend, mainly, on two factors: 1) on what aim the compilers set themselves and 2) what decisions they make concerning the extent to which obsolete, archaic, dialectal or highly specialised meanings should be recorded, how the problem of polysemy and homonymy is solved, how cases of conversion are treated, how the segmentation of different meanings of a polysemantic word is made, etc.
It is natural, for example, that diachronic dictionaries list many more meanings than synchronic dictionaries of current English, as they record not only the meanings in present-day use, but also those that have already become archaic or gone out of use. Thus SOD lists eight meanings of the word arrive (two of which are now obsolete and two are archaic), while COD gives five.
Students sometimes think that if the meaning is placed first in the entry, it must be the most important, the most frequent in present-day use. This is not always the case. It depends on the plan followed by the compilers.
There are at least three different ways in which the word meanings are arranged: in the sequence of their historical development (called historical order), in conformity with frequency of use that is with the most common
