Here are few more election-related words:
Hung parliament – a parliament in which no political party has an absolute majority of seats, as is the case with the UK parliament after yesterday’s election. This term was first used in Britain in 1974, but hang or hung has been used to indicate a situation that’s indecisive since at least the 14th century, when it was became linked to the idea of suspense. The phrase ‘hung jury’, i.e. one that cannot agree, has been used in the USA since 1848 [source].
Coalition – was first used in a political sense in 1715 and comes from the Latin Latin coalitus (fellowship) via the French coalition. Coalitus was originally the past participle of Latin coalescere, which is a combination of com- (together) plus alescere (to grow up).
The Welsh equivalents of these words are:
Senedd grog = hung parliament: senedd = parliament, senate; crog = hanging, pendant, suspended, pendent, pendulous, pensile
Clymblaid = clique, coterie, coalition: clym- probably comes from clymu = to tie; plaid = party, faction.
Plaid is also the root of pleidlais = vote (llais = voice); pleidleisio = to vote; pleidleisiwr = voter.
