「#473. 意味変化の典型的なパターン」 ([2010-08-13-1]) で意味の一般化 (generalization) と特殊化 (specialization) について触れた．別の言い方をすれば，意味の拡大 (widening) と縮小 (narrowing) である．英語史からの意味の伸縮の例が一覧できると便利だと思っていたところ，Williams にいろいろと挙げられていたので掲載しよう．

ここに挙げた事例数からも推測されるように，意味の拡大と縮小の例を比較すると，縮小の例のほうが一般的に多いもののようだ．その理由は定かではないが，時代とともにあらゆるものが分化していく速度のほうが，それら断片を総合しようとする人間の営為よりも勝っているからかもしれない．概念階層 (cf. 「#1962. 概念階層」 ([2014-09-10-1])) の観点からみれば，下位語 (hyponyms) を作り出し，枝を下へ下へ伸ばしていくことは半ば自動的に進むが，新たな上位語 (hypernyms) を作り出す統合の作業には労力が要る．学問も，ひたすら細分化していきこそすれ，総合の機会は少ない・・・．Williams (177) は，次のような見解を述べている．
It is harder to find a pattern for widening than it is for narrowing. It is not entirely certain, but meanings seem to widen somewhat less frequently than they narrow. As a culture becomes more diversified and more complex with more areas of knowledge and activity, those areas require a vocabulary. Because every language has a finite number of words and because speakers are not inclined to coin completely new forms for new concepts, the simplest way to deal with new areas of knowledge is to use the current vocabulary. Borrowing, derivation, compounding, and so on operate here. But perhaps even more frequent is narrowing.
But on the other hand it can also be difficult to talk about the most ordinary activities of daily life as they diversify. Once it becomes possible to drive (drive originally meaning to force an animal along), or ride (ride originally meaning to go on horseback), or walk (originally meaning to travel about in public), then talking about getting some place without specifying how becomes difficult. The word go, originally meaning to walk, generalized so that an English speaker can now say I am going to town this morning without having to specify how he gets there. Carry generalized from transporting specifically in a conveyance of some sort to transporting by bearing up in general: The wind carried the seed, and so on.
上掲の一覧には，広い意味と狭い意味が完全に推移 (shift) しきった例ばかりではなく，古いほうの語義も残存し，新旧が並存している pill や sanctuary などの例も少なくない．
