Dean：Today we study the word “edible”. Edible means “safe to eat”. It also means “something you can eat”. Easy words: you can eat it. Moli, how do you understand it in Chinese?
2
,900 --> ,339
茉莉：“edible”的意思是：可以吃的、能入口的，而且通常是对人安全的食物。English meaning: safe to eat. 这个词是什么词性，常怎么用？
3
,839 --> ,799
Dean：Edible is an adjective. We use it to talk about food or things you can eat. Now let’s use an example to learn it. Example 1: The fish is edible, but it is not fresh.
4
,299 --> ,500
茉莉：这句话的意思是：这条鱼是可以吃的，但它不新鲜。这里的 edible 指的是“对人来说安全、能吃”的意思。想一想更简单的英文，你会怎么说这句里 edible 的感觉？
5
,000 --> ,640
Dean：In this sentence, “edible” sounds like “safe to eat”. It does not talk about taste or smell. Example 2: This fruit is edible, even for beginners to try.
6
,140 --> ,900
茉莉：这句话的意思是：这种水果是可以吃的，新手也可以尝试。这里的 edible 用来说明“能不能吃”，而不是好不好吃。Dean, can you explain the sentence in simpler English?
7
,400 --> ,960
Dean：It means the fruit is safe to eat. “Edible” helps us know it is okay for food. Example 3: Only take edible parts of the plant.
8
,460 --> ,620
茉莉：这句话的意思是：只拿植物里可以吃的部分。这里的 edible 是用在“植物的某些部位是否能吃”的情况。接下来讲词根词缀与词源。
9
,120 --> ,719
Dean：Moli, in “edible,” what are the word root, the affixes, and what is the etymology? Tell it like you are building the word step by step.
10
,219 --> ,620
茉莉：好，我们先把 edible 拆开想。它看起来像是由两部分拼起来的：一个是 ed，和“吃”有关；另一个是 ible，常常出现在形容词里，用来表示“可以……的、适合……的”。所以 edible 就像在说“能被吃的东西”。你可以把它理解成“可食用”的意思，是一种很实用的判断：这东西入嘴之后算不算能吃、合不合适。 再说点“像亲戚一样”的词。比如 credit 这类词不是同样的部分来源，但大家会发现拼法里也有那种“看起来很像”的结构。更接近同族思路的其实是那些以 ed 开头并和吃、处理食物有关的词，虽然它们的具体形态会变化，比如有的更偏向“饮食动作”，有的偏向“可被吃的结果”。它们之间的区别通常在于：edible 更强调结果和状态，也就是“能不能吃”，而别的同类词可能更强调“过程”或“行为”。 最后讲身世故事。edible 来自拉丁语的 edere，原意和“吃、取食”紧密相关。后来语言演化时，拉丁语的表达方式逐渐被吸收进法语和英语体系里，那个表示“可以……的”的形容词感慢慢稳定下来，最后在英语里形成 edible 这种固定用法。于是它从“与吃有关”的根源意义，逐渐变成今天这种“可以安全食用”的判断词。 我觉得最有趣的是：它的意思不是凭空来的，而是从“吃”的古老根出发，再加上“可……的形容词感”，一步步变得很直接、很生活化。下一部分我们就来讲搭配、常见场景和互动方式。
11
,120 --> ,280
Dean：Great! So what did this word originally mean, and how did it become the word we use today for “safe to eat”?
12
,780 --> ,500
Dean：Yesterday, you open a small kitchen box from a friend. You want to try the snack, but the label is missing. You look at it and think, “Is it edible?” What collocations can we use for this kind of situation?
13
,000 --> ,519
茉莉：第一个搭配是 edible food。它的语感很直接，就是把 edible 当作“可食用的、能吃的食物”的判断。日常里你会更自然地说某种食物是 edible food，尤其当你在强调“能不能吃”而不是“好不好吃”。如果对方给你的是不确定来源的东西，这个搭配会更贴合你刚才说的那种焦虑感。
14
,019 --> ,859
Dean：In this case, you can say: “Is it edible food?” Example: “Only give it edible food for the cat.”
15
,359 --> ,559
茉莉：在这种场景说 edible food 很自然，因为你在讲“喂给猫的东西是不是能吃的”。这里的 edible 用来做安全性和适用性的判断，比起只说 edible，你会更具体地指向“食物”本身。
16
,059 --> ,499
Dean：Now imagine you are at school for a science lab. You have to write a safety rule on the wall. Your teacher says, “Do not put anything in your mouth.” Then they mention, “Only edible things are allowed.” What collocation fits this school rule?
17
,999 --> ,319
茉莉：第二个搭配是 edible parts。意思是“可食用的部分”，常用于植物、食材或者某个物体的“部位”层面。它的语感有点像在做分类：哪些部分可以吃，哪些部分不行。你在写实验或安全规则时用它，会特别清楚、很有条理。
18
,819 --> ,539
Dean：You can say: “Only the edible parts are safe.” Example: “Peel off the skin. The edible parts are inside.”
19
,039 --> ,919
茉莉：edible parts 这里特别自然，因为你在讲“去皮之后哪些是能吃的部分”。如果你想更精确描述“部分”，用 parts 比用 food 更贴合，也更符合你刚才的学校场景和规则写法。
20
,419 --> ,699
Dean：Last one. You watch a news video about a street market. The sellers say, “Our product is edible.” People ask, “Is it safe to eat?” It is not about taste. It is about safety. What collocation would you expect in such news?
21
,199 --> ,639
茉莉：第三个搭配是 edible product。它的语感更像在新闻或公告里，因为 product 更正式、更接近“产品/商品”的表达。你用 edible product 来强调“这个东西作为产品是可以食用的”，跟我们平时说 edible food 的日常口语相比，会更偏公共信息。
22
,139 --> ,059
Dean：In news, you may hear: “This edible product is safe to eat.” Example: “The company says the edible product is tested.”
23
,559 --> ,999
茉莉：edible product 很适合新闻语境，因为它是对“商品”的判断，而不是对某个人做饭的日常评论。这里的 tested 通常指检测过，整体语气更正式。
24
,499 --> ,099
Dean：Now your turn. If you see “edible” next to “parts,” which collocation should you use? Think of plants or food portions. Or you can make one sentence for listeners: choose one collocation and write a simple sentence. What will you say, Moli?
25
,599 --> ,759
茉莉：好的，我来复述互动问题。你需要在听到 “edible” 和 “parts” 放在一起时选出对应搭配，也就是用来表示“可食用的部分”。或者你也可以用一个搭配造一个简单句。重点是让句子体现出你在判断“能不能吃”，而不是在说味道。接下来想了解这个词和它的近义词有什么区别，所以你们可以先试着说你选的搭配和句子给我听。
26
,259 --> ,019
Dean：What are some common synonyms of “edible”? How are they different in usage?
27
,519 --> ,719
茉莉：“edible”的常见近义词可以有：eat able、consumable、fit to eat、safe to eat、tolerable（更偏“能入口、勉强可吃”但不强调好吃或一定安全）。我们一个一个来对比，先看第一个。
28
,219 --> ,819
Dean：OK, what is the first synonym? How should I use it correctly?
29
,319 --> ,919
茉莉：第一个是 eat able。它的意思和 edible 很接近，指“可吃的”。但它更像把意思分开来讲，形式上不如 edible 标准自然，所以日常更建议你用 edible。适用场景：你想强调“能不能吃”时，但在大多数正式和自然表达里用 edible 更好。例句：This snack is edible, so it is eat able for everyone.
30
,419 --> ,219
Dean：Got it. What about the next synonym? How is it different?
31
,719 --> ,119
茉莉：第二个是 consumable。它强调“可以被消耗/食用的”，有一点更“功能性”的感觉，常见于说明书、清单、管理类语境。适用场景：食品安全、仓储、使用规定、成分是否适合食用。语气上通常比 edible 更偏正式或偏“规则语言”。例句：Only consumable items are allowed in this room.
32
,619 --> ,339
Dean：Thanks. And the third synonym?
33
,839 --> ,879
茉莉：第三个是 fit to eat。它更强调“符合可食用标准”，常用于判断食物是否合格或是否适合被吃，但不一定像 edible 那样总是简短直接。适用场景：你看到变质迹象、检查标签、或做更认真标准的判断时。语气通常更严谨。例句：The fruit looks old, but is it fit to eat?
34
,379 --> ,059
Dean：OK. Is there a fourth synonym we should know?
35
,559 --> ,239
茉莉：第四个是 safe to eat。它和 edible 最接近，但重点会更明确地放在“安全性”。适用场景：当你想告诉别人“不要担心，有风险吗”，尤其是食品安全、医疗/营养建议、公告类信息。语气上通常比 edible 更强调“风险控制”。搭配上你更常看到 safe to eat food 或 safe to eat products。例句：When in doubt, choose food that is safe to eat.
36
,739 --> ,219
Dean：Great. If there are no more, can you summarize when to use which word?
37
,719 --> ,919
茉莉：总结一下：如果你想说“能吃、可食用”的一般判断，用 edible 最自然。想更正式、更像规定或清单，用 consumable。想强调“是否达标、是否符合可吃标准”，用 fit to eat。想把重点放在“安全性”，用 safe to eat。最后一部分我们来轻松一下，讲个和这个词相关的幽默小故事。
38
,419 --> ,579
Dean：We have learned so much. Now let’s relax with a fun short story related to “edible”.
39
,079 --> ,639
茉莉：什么故事？我很期待！
40
,139 --> ,779
Dean：It’s Monday morning at my office. In the break room, there is a big box of snacks. The label says, “edible product.” But the box has no brand. My boss looks serious and says, “Only edible products are allowed.”
41
,279 --> ,879
茉莉：听起来有点像规则办公室！然后呢？你们真的都不敢吃吗？
42
,379 --> ,899
Dean：Then my coworker, Alex, opens the box and says, “Relax! Look, it is edible food.” He picks one snack and smiles. But I notice something. The snack has a sticker: “Only edible parts.”
43
,399 --> ,679
茉莉：哇，原来还要分“能吃的部分”！那你们怎么做的？
44
,179 --> ,339
Dean：So we start a safety mission. Alex tries one piece. I check the sticker. My boss says, “If it is not edible parts, do not put it in your mouth.” Finally Alex finds the tiny “edible part” at the corner. He takes it… and it tastes like “office dust,” but at least it was safe.
45
,839 --> ,399
茉莉：哈哈！这个故事的笑点是：大家先被“edible product”的正式感吓到，又用“edible food”和“edible parts”来判断。最后发现“安全”不一定等于“好吃”，但至少规则很有用！
46
,899 --> ,099
Dean：Today we used “edible” in real moments: “edible food,” “edible parts,” and “edible product.” We also learned the idea of focus: eatable things, the right parts, and safety. Thanks for listening. See you next time, and remember: be curious, and stay safe when you eat!
