The word "forth" does not have a comparative form, as it is an adverb that indicates movement away from a place or a point in time. Comparatives typically apply to adjectives or adverbs that can express varying degrees, such as "fast" becoming "faster." Since "forth" doesn't describe a quality that can be compared, it remains unchanged.

Ordinarily, you'd expect northerner for the comparative of northern, but there is a very common noun northerner, which may be why the Frenchified "more northern" is the usual form. Again, you'd expect northerrnest as the comparative, but with directions, such as northern and southern, top and bottom, upper and outer and so forth, the superlative is usually formed by adding -most: northernmost, uppermost etc.
