What is Long-short-short in poetic meter?

In poetic meter, "long-short-short" refers to a specific rhythmic pattern known as a "dactyl". A dactyl consists of one stressed syllable followed by two unstressed syllables. It is commonly used in poetry, especially in classical Greek and Latin verse, as well as in some modern poetry.

The pattern can be represented as:

```

stressed syllable (/) - unstressed syllable (U) - unstressed syllable (U)

```

For example, the word "poetry" follows the dactyl pattern:

```

/POE/ - U - U

```

When describing poetic meter, the terms "long" and "short" refer to the relative duration or weight given to each syllable in the pattern. In traditional scansion, a long syllable is considered to take twice as much time to pronounce as a short syllable.

Poets use different combinations of long and short syllables to create rhythmic patterns and variations in their poetry. The use of dactyls and other rhythmic patterns can add musicality, emphasis, and expressiveness to poetic lines.
