Etymology: "Coulters" is simply the plural of "coulter", the blade fixed in front of a plough share that slices vertically through the soil ahead of it. The singular is the older form, and the plural follows the usual English pattern of adding -s to a countable noun, so there is nothing further to unpack in the ending itself. The word comes to English from Latin "culter", meaning "a knife", which Old English took over as "culter" and Middle English carried forward. The sense was already plain in Latin: a cutting edge, nothing agricultural about it. The farming meaning is simply the knife's job applied to the field, the blade doing in the earth what a kitchen knife does to bread. The English form also shows a sound change that the word shares with "poultry". Both passed through French-influenced spellings where the Latin "c" softened in pronunciation, which is why the word looks further from its Latin source than its meaning suggests.
