1. The Core Difference
| Phrase | Function | Typical Use | Example |
|---|---|---|---|
| All these | Directly modifies the noun without a preposition | When the noun follows immediately after the adjective | All these books are overdue. |
| All of these | Uses the prepositional phrase “of these” to add emphasis or clarify scope | When you want to stress the completeness or when the noun is far from the adjective | All of these books are overdue. |
- All these feels tighter and more conversational.
- All of these feels slightly formal or emphatic.

In spoken English, all of these can sound cumbersome because of the extra syllable. Native speakers often elide the “of” in casual conversation:
- All these → All these (normal)
- All of these → All these (when speaking fast)
Even so, in formal writing or public speaking, keeping “of” can add a layer of emphasis that feels intentional.

| Situation | Phrase | Tone |
|---|---|---|
| Casual, everyday | All these | Informal, conversational |
| Formal report | All of these | Formal, emphatic |
| Highlighting totality | All of these | Strong emphasis |
| Quick list | All these | Light, straightforward |
Use all of these when you want to underline that nothing is left out. It’s a subtle way to command attention.
