SENATOR, in general, denotes a member of some senate.
Among us, senator is a member of parliament. In the laws of king Edward the Confessor, we are told, that the Britons called those senators, whom the Saxons called afterwards aldermen and borough-masters; tho' not for their age, but their wisdom; for some of them were young men, but very well skilled in the laws. Kenulph king of the Mercians granted a charter, which ran thus, viz. Consilio et consensu episcoporum et senatorum gentis sue largitus fuit dño monasterio, &c.
In Scotland, the lords of session are called senators of the college of justice.
