LatNS and LongWE

LatNS and LongWE
A good way to remember
1) Latns that Latitude is for North and South is to use the word I made up Latns. Like Latins. Remember Latns for latitude North South.
2) LongWe that Longitude is for West and East is to use the word I made up LongWE.
Lines of Latitude are the imaginary horizontal lines shown running east-to-west (or west to east) on maps (particularly so in the Mercator projection) that run either north or south of the equator. Technically, latitude is an angular measurement in degrees (marked with °) ranging from 0° at the equator (low latitude) to 90° at the poles (90° N or +90° for the North Pole and 90° S or −90° for the South Pole)
A circle of latitude, on the Earth, is an imaginary east-west circle connecting all locations (not taking into account elevation) that share a given latitude. A location's position along a circle of latitude is given by its longitude. Circles of latitude are often called parallels because they are parallel to each other. On some map projections, including the Equirectangular projection, they are drawn at equidistant intervals.

Longitude identified by the Greek letter lambda (λ), is the geographic coordinate most commonly used in cartography and global navigation for east-west measurement. Constant longitude is represented by lines running from north to south. The line of longitude (meridian) that passes through the Royal Observatory, Greenwich, in England, establishes the meaning of zero degrees of longitude, or the prime meridian. Any other longitude is identified by the east-west angle, referenced to the center of the Earth as vertex, between the intersections with the equator of the meridian through the location in question and the prime meridian. A location's position along a meridian is given by its latitude, which is identified by the north-south angle between the local vertical and the plane of the equator.
