yoú cǐ · HSK 5
from this
➡️ 由此 = from + this; 由 (from/by) + 此 (this)
由 marks the source or cause (from, by, through); 此 is a formal word for this. Together: from this point, hereby. Often opens a formal conclusion: 由此可见 = from this it can be seen.
由 — pictograph of a gourd or vessel with a stem
由 originated as a pictograph showing a gourd, fruit, or vessel with a sprout or stem emerging from the top. Over time the meaning shifted abstractly to 'come forth from' or 'origin', giving modern senses like 'reason', 'cause', and 'from'. It is unrelated to 田 despite the visual similarity.
此 — foot 止 + spoon/person 匕
此 originally depicted a person (匕) standing with a foot (止), suggesting 'to stop here' or 'this place.' Over time the meaning generalized from a specific location to the demonstrative pronoun 'this.' The foot component still hints at the original sense of standing in a particular spot.
