A stem is a plant’s stalk, and it’s also a verb meaning “grow out of.” So roses have stems , and your idea to give roses to your mom for her birthday stems from her love of flowers.
A stem can be the central root of a word, the supporting structure of a plant, or the thin, cylindrical part of a glass goblet. When one thing stems from something else, it originates or begins growing there: “His vegetarianism stems from his love of animals.” An older meaning of the verb is “stop the flow of something,” as in “Stem your nosebleed with this tissue!” or “Some people think streetlights will stem the graffiti on that street.”
stem from something 源于，来自，由…引起

名词 ：
植物的茎 ： The stem of a plant.(脑)干 ： The brainstem.高脚杯的脚 ： The stem of a wine glass.
动词 ：
阻止 ： To stop or restrict, e.g., stem the flow.源于 ： To originate or develop as a consequence, e.g., “His success stems from hard work.”
名词 ：
植物的茎 ：The rose stem is covered with thorns. (玫瑰的茎上布满了刺。)(脑)干 ：The doctor explained the damage was in the patient’s brainstem. (医生解释说损伤发生在患者的脑干。)高脚杯的脚 ：She carefully polished the stem of the wine glass. (她仔细擦亮了高脚杯的脚。)

from stem to stern ：从头到尾，彻底地（源自航海术语，指从船头到船尾）
Example: The ship was cleaned from stem to stern. (船从头到尾都清洗了一遍。)
联想记忆法 ：
把stem 想象成植物的主干，你可以联想到植物的很多部分都是从茎开始生长的，这样你可以记住“源于”的意思。
同时把stem 想象成一个高脚杯的脚，容易理解它是一个支撑的结构。
造句练习 ：
尝试每天用stem 造句，涵盖不同的意思。例如：
“The stem of the tree was very thick.”（树干非常粗。）
“The idea stems from a desire to improve the system.”（这个想法来自于想要改进系统的愿望。）
视频记忆 ：
通过你提供的视频片段加深理解。例如，看到某人询问“long-stemmed red roses”时，就能联系到“植物的茎”的含义。
“stem”一词源自古英语的“stēam”，意为“支柱”或“支撑”。它的词源跟德语中的“Stamm”以及荷兰语中的“stam”相似，均有“主干”或“支撑”的意思。
希望这些解释和技巧能够帮助你更好地记住和使用“stem”这个单词。如果有更多的单词需要解释，请随时告诉我！
