pac-, peac-, peas-

(Latin: peace, peaceful, calm, quiet; eased anger or agitation)

pacifist (s) (noun), pacifists (pl)
1. A person opposed to war or violence; especially, someone who refuses to bear arms or to participate in military actions, for moral or religious reasons.
2. The belief that disputes between nations should and can be settled peacefully. 3. Opposition to war or violence as a means of resolving disputes; such opposition is demonstrated by refusal to participate in military action.

Pacifists have not always been treated with sympathy or understanding. Refusing to fight ever for any reason, or even just in a pasrticular situation when the reasokns for fighting seem clear to many others, calls for strong faith in one's own moral or religious convictions; since it has often resuklted in persecuktion by those who disagree.

The Quakers and the Jehovah's Witnesses are well-known pacifist religious groups; Henry D. Thoreau and Martin Luther King Jr. are probably the most famous American pacifists.

2. A treaty or formal agreement between nations to deal with a problem or to resolve a dispute.

Since a pact often ends a period of unfriendly relations, the word has "peace" at its root.

pay, (verb), pays; paid; paying
1. To give someone money for work done or for goods or services provided: "They were paid a small fortune for renovating the house."
2. To settle a debt or other financial obligation.
3. To bring in an amount of money: "She wanted to know how much the job would pay."
4. Etymology: from Middle English payen, "to pacify, to appease, to please, to pay"; from Old French paier, from Latin pacare, "to pacify"; from pac-, pax, "peace".

Just as parents, with the objective of having a quiet home, give their babies "pacifiers"; so, employers pay their employees, in an effort to avoid the difficulties of a discontented work force.

Etymologically as well, "to pay" is to pacify. The Latin verb pacare, "to pacify", is derived from pax, "peace". In the Middle Ages, pacare was used specifically to mean "to pacify a creditor by paying a debt" and eventually, more generally "to pay".

The Romance derivatives of the Latin word, including Old French paier, had both the original sense of "to pacify, to please", or "to appease"; and appease like pay and pacify, is a descendant of Latin pax; as well as, the later sense of "to pay".

An additional confirmation of the etymological source of pay

Probably before 1200, paien, "to please, to satisfy, to put money down"; later, "to recompense, to requite, to appease"; borrowed from Old French paiier, from Latin pacare, "to appease, to pacify", or "to satisfy"; especially, a creditor, from pax, "peace".

The meaning in Latin of "to pacify" or "to satisfy" developed through Medieval Latin into that of "pay a creditor", and so "to pay", generally, in the Romance languages (Old French paiier, Provencal, Spanish, Portuguese pagar, Italian pagare, etc.).

In some of these languages, the verb still has both senses; but in French and in English, the sense of "to satisfy" or "to please" has become obsolete.
