Implement Excerpt Generator for Word Content and Use in SEO Meta Description

Currently, each word's content in the Astro project lacks a meta description, which is crucial for search engine optimization (SEO) and improving discoverability. To enhance this, we should implement an excerpt generator that extracts a concise summary from each word's content and uses it as the meta description value.

#### Task
1. **Excerpt Generation**:
- Implement a function or logic to generate a concise excerpt from the content of each word in the Astro project.

2. **Integration with Meta Description**:
- Update the `word.astro` layout to utilize the generated excerpt as the meta description.

#### Implementation Steps
1. **Excerpt Logic**:
- Develop a method to extract a summary or snippet from the content of each word.
- Consider factors such as length, readability, and relevance to ensure the excerpt effectively summarizes the content.

2. **Meta Description Integration**:
- Modify the `word.astro` layout to incorporate the generated excerpt as the meta description tag.

#### Acceptance Criteria
- Each word's content should have a dynamically generated excerpt.
- The generated excerpt should be integrated into the `word.astro` layout as the meta description.

#### Additional Information
Implementing an excerpt generator will improve SEO by providing meaningful meta descriptions for each word's page, aiding in better search engine ranking and user engagement.

Start by reading the word.astro layout and the word content structure in the Astro project. Determine how an excerpt can be generated and what length and formatting are appropriate, then verify that each word page exposes the generated excerpt as its meta description.
