further

记忆单词“further”可以使用以下方法：

想象“further”的“f”像是向前的箭头，“ur”代表一个正向的推进动作，“ther”可以想象为“there”的简化，意味着进一步向那个方向前进。这样，“further”就可以形象地理解为“进一步向前走”或“更远的地方”。

further 较远

用做far的比较级。

further

further: [OE] Etymologically, further is simply a comparative form of forth, and originally meant nothing more than simply ‘more forward’. Its more metaphorical senses, ‘in addition’ and ‘to a greater extent’, are secondary developments. It was formed in the pre-historic Germanic period, and so has relatives in other Germanic languages, such as German vorder. Its verbal use is apparently equally ancient.
=> forth

further (adv.)

Old English furðor, forðor "to a more advanced position, forward, onward, beyond, more distant; farther away; later, afterward; to a greater degree or extent, in addition; moreover," etymologically representing either "forth-er" or "fore-ther." The former would be from furðum (see forth) + comparative suffix *-eron-, *-uron- (compare inner, outer).

Alternative etymology (Watkins) traces it to Proto-Germanic *furthera-, from PIE *pr-tero- (source also of Greek proteros "former"), representing the root *per- (1) "forward, through" (see per) + comparative suffix also found in after, other. Senses of "in addition, to a greater extent" are later metaphoric developments.

It replaced or absorbed farrer, ferrer as comparative of far (itself a comparative but no longer felt as one). Farrer itself displaced Old English fierr in this job; farrer survived until 17c., then was reduced to dialect by rival farther. "The primary sense of further, farther is 'more forward, more onward'; but this sense is practically coincident with that of the comparative degree of far, where the latter word refers to real or attributed motion in some particular direction." [OED]

further (v.)

Old English fyrðran, fyrðrian "to impel, urge on; advance, promote, benefit;" see further (adv.). Compare Middle Low German vorderen, Old High German furdiran, German fördern, probably from their respective adjectives via the notion in phrases such as Old English don furðor "to promote." Related: Furthered; furthering. After the further/farther split, this sense also continued in a shadow verb farther (v.), attested from 16c. but apparently dying out 19c.

further (adj.)

Old English furðra "further, greater, superior," probably a prehistoric derivative of further (adv.). Compare Old Frisian fordera, German vorder "that is before another." In early Middle English it also meant "earlier, former, previous;" a great-grandfather was a furþur ealdefader (12c.), and a previous wife was referred to legally as a forther wife.

【further, farther】
这组词都有“更远(地)，进一步(地)”的意思，其区别是：
further: 也是far的比较级(作为副词，有人认为是fore或forth的比较级)，按传统的观点，further表抽象的程度或数量的更进一步，不表实际距离。但现代英语，尤其在非正式语体中，这两个词的意思实际上已没有区别，而且further用得更广泛一些。
farther: 是far的比较级，指距离、空间或时间上的较远；有时也可指数量上或抽象的程度上的进一步，但不如further普通。

【further, promote, contribute, push, advance】
这组词都有“促进，推进”的意思，其区别是：

promote: 指在某一进程的任何时期或阶段提供积极的帮助与支持。
contribute: 指能促进事物向前发展的因素，但这种因素并非决定性的。
push: 口语用词，通常指利用自己的活动或影响推进某事。
advance: 通常指为加速某一进程或达到某个预期目的而给予有效的促进，强调作出有意识、决定性的努力。
