井戸, 泉, and 貯水池: Wells, springs, and reservoirs
Compare drawing water from a well, resting beside a spring, and rainwater stored in a reservoir, while following the clear spring, secure lid, and water-level checks.
Names for three water-related places
井戸 (いど) means a well, 泉 (いずみ) a spring, and 貯水池 (ちょすいち) a reservoir. Their examples connect to drawing water, resting beside a spring, and storing rainwater or checking its level. Read the named objects without classifying them solely by depth, size, or legal use.
「庭の古い井戸から水をくみ上げた。」 means “We drew water from the old well in the yard.” A separate example, 「使われなくなった井戸に安全なふたをした。」, means “We placed a secure lid over the unused well.” The lid is what is described as secure; neither sentence describes drinking the water.
A clear spring and stored rainwater
「森の奥に澄んだ泉がありました。」 means “There was a clear spring deep in the forest.” 「旅人は泉のそばで短い休息を取った。」 describes the traveler resting briefly beside the spring. A clear spring and rest beside it are stated, without an added claim that the traveler drank its water.
「山のふもとの貯水池に雨水が蓄えられている。」 means “Rainwater is stored in the reservoir at the foot of the mountain.” 貯水池 is the storage place and 雨水 the stored water. Keep the name, object, and activity separate from drawing water at the well or resting beside the spring.
Checking a level and following the modifiers
「作業員が貯水池の水位を毎朝確認する。」 means “Workers check the reservoir's water level every morning.” 毎朝 describes the repeated checks, and 水位 is their object. Checking the level does not establish that workers adjusted it or maintained a constant level.
Connect drawing water to 井戸, resting beside the spring to 泉, and storage or checking to 貯水池. Clear describes the spring, and secure describes the lid over the well. These descriptions do not supply drinking-water standards or a safety judgment for the entire facility.
What do 井戸, 泉, and 貯水池 name in the drawing, resting, and storage examples?
Show the answer and why
井戸 is a well, 泉 a spring, and 貯水池 a reservoir. The examples describe drawing water, resting beside a spring, storing rainwater, and checking its level. They do not turn a clear spring into water someone drank or a level check into completed level control.
