# Words for Different Levels of “Weak”: From Delicate to Incapacitated

> Source: https://mem-app.com/blogs/words-for-different-levels-of-weak (Mem-App blog, 2026-10-22)

“Weak” is one of the first adjectives we learn, and it ends up doing far too much work. A tired friend, an elderly relative and someone badly hurt in an accident are all “weak”, but they are very different situations. Native speakers choose different words depending on how serious the weakness is. In this post I'll walk you through six words, from mild to severe, so you can say exactly what you mean. I'm focusing on physical weakness here, so “a weak argument” will have to wait for another post.

## The ladder at a glance

| Level | Word | Roughly means |
|---|---|---|
| 1 | **delicate** | easily harmed, needs care |
| 2 | **shaky** | unsteady, not fully strong |
| 3 | **frail** | physically weak, from age or illness |
| 4 | **feeble** | very weak, almost no force |
| 5 | **debilitated** | seriously weakened by illness or injury |
| 6 | **incapacitated** | too weak or hurt to function |

## 1. delicate

**UK** /ˈdel.ɪ.kət/ · **US** /ˈdel.ə.kət/ · *Adjective*

**Meaning:** Easily damaged or hurt, and needing careful handling.

**Examples:**

- Be careful, this vase is very delicate.
- She has a delicate stomach, so she avoids spicy food.

**Synonyms:** fragile, sensitive, dainty  
**Opposites:** sturdy, robust

**Tip:** This is the gentlest word on the ladder. It can describe objects, health or situations, and it isn't negative. It simply means "handle with care".

## 2. shaky

**UK** /ˈʃeɪ.ki/ · **US** /ˈʃeɪ.ki/ · *Adjective*

**Meaning:** Unsteady and not fully strong, often because of illness or nerves.

**Examples:**

- I felt shaky after three days with the flu.
- His hands were shaky before the interview.

**Synonyms:** unsteady, wobbly, trembling  
**Opposites:** steady, firm

**Tip:** Very common in everyday speech. It usually describes a temporary state, such as after being ill, scared or hungry.

## 3. frail

**UK** /freɪl/ · **US** /freɪl/ · *Adjective*

**Meaning:** Physically weak and easily hurt, usually because of age or illness.

**Examples:**

- My grandmother is frail, so we walk slowly.
- He looked frail after a long stay in hospital.

**Synonyms:** weak, fragile, infirm  
**Opposites:** strong, sturdy

**Tip:** Often used for elderly or ill people, and it's more lasting than *shaky*. It's respectful and gentle, so it works well in polite conversation and in the news.

## 4. feeble

**UK** /ˈfiː.bəl/ · **US** /ˈfiː.bəl/ · *Adjective*

**Meaning:** Very weak, with almost no strength or force.

**Examples:**

- He gave a feeble wave from his bed.
- The old man's voice was thin and feeble.

**Synonyms:** weak, frail, faint  
**Opposites:** powerful, vigorous

**Tip:** Stronger than *frail*, and it can sound a little negative. It's more common in writing and stories than in casual speech, so be careful when describing a real person to their face.

## 5. debilitated

**UK** /dɪˈbɪl.ɪ.teɪ.tɪd/ · **US** /dɪˈbɪl.ə.teɪ.t̬ɪd/ · *Adjective*

**Meaning:** Seriously weakened, especially by illness or injury.

**Examples:**

- The virus left him debilitated for weeks.
- She was too debilitated to go back to work.

**Synonyms:** weakened, drained, enfeebled  
**Opposites:** energised, robust

**Tip:** A more formal word you'll meet in news, health and work contexts. It often points to a cause, such as an illness or an injury.

## 6. incapacitated

**UK** /ˌɪn.kəˈpæs.ɪ.teɪ.tɪd/ · **US** /ˌɪn.kəˈpæs.ə.teɪ.t̬ɪd/ · *Adjective*

**Meaning:** So weak or badly hurt that you cannot do normal activities.

**Examples:**

- A back injury left him incapacitated for a month.
- She was completely incapacitated by the fever.

**Synonyms:** disabled, immobilised, laid up  
**Opposites:** able, fit

**Tip:** The top rung, and quite formal. You'll see it in medical, legal and news language when someone simply can't function.

## How to remember them

Reading a list once isn't enough, because you'll forget most of it within days. That's why I built Mem-App around **spaced repetition**. You review each word just as you're about to forget it, and the gaps between reviews grow as the word sticks.

1. **Look up** each word in Mem-App's built-in dictionary to see definitions, examples, synonyms, opposites and both US and UK pronunciation.
2. **Add it to your list** with one tap.
3. **Review and rate** each word as Easy, Good, Hard or Forgot. Mem-App adapts the next review to how you're doing.
