Clodgy has an interesting meaning and goes back to the time when there were 'lazar-houses' in Cornwall to keep the infectious such as lepers out of town. There is such a one attested for St Ives. Clodgy comes from the Cornish words 'Klav' (sick) and 'Chi' (house) which mutates to 'Ji' so 'Klavji' = sick-house or hospital (in modern usage).
