Learn English – The use of “that of” and an apostrophe

Round in an old term and it is not generally written as 'round

Round vs around:

• Round works virtually anywhere around would work. The reverse is not true, as round has a number of definitions it doesn’t share with around. For example, it wouldn’t work to say that the edge of a circle is around, and I wouldn’t invite you to play an around of golf.

• But even though round works as a breezier alternative to around, round tends to create a casual tone, so around is usually safer in serious or formal writing.

• British writers in particular are wont to use round in place of around. This substitution does occur in American English, but much less often.

Round etymology:

• late 13c., from Anglo-French rounde, Old French roont (12c., Modern French rond), probably originally *redond, from Vulgar Latin *retundus (source also of Provençal redon, Spanish redondo, Old Italian ritondo), from Latin rotundus "like a wheel, circular, round," related to rota "wheel" (see rotary).

• As an adverb from c. 1300; as a preposition from c. 1600. In many uses it is a shortened form of around. The French word is the source of Middle Dutch ront (Dutch rond), Middle High German runt (German rund) and similar Germanic words.
