century
When referring to time, we usually use ordinal numbers (like 19th century) rather than cardinal numbers (like 19 century). In sports, specifically cricket, the term is used as a common noun and does not require capitalization unless it starts a sentence. Note that while 'century' usually means 100 years, in historical contexts like the Roman army, the size of a 'century' could vary slightly from exactly 100 men.

Chloe uses the slang 'legit' to emphasize her struggle, while Karen uses the phrasal verb 'grind it out' (to work hard at something tedious) and 'lagging behind' to express her characteristic pressure on her daughter.
