hurdler

the word 'hurdler' is a transparent english formation, combining the noun 'hurdle' with the agentive suffix '-er'. the term 'hurdle' itself originates from old english hyrdel, which referred to a temporary frame or wickerwork barrier used in fencing or animal enclosures. this concrete sense of a barrier evolved metaphorically into the athletic obstacle used in track and field by the early 19th century. the '-er' suffix, a prolific germanic agent-noun formative, simply attaches to create a word for 'one who jumps or races over hurdles', illustrating a clear and logical compounding process within the english language.

Structure: hurdle + er hurdle (origin: old english hyrdel, meaning a portable frame or barrier; functional role: base noun) + er (origin: old english -ere, agent noun suffix; functional role: derivational suffix denoting 'a person or thing that does something').
