However, we can look at reconstructed words and compare them to their descendants in modern languages to illustrate the concept.
Example:
* Reconstructed Proto-Indo-European: *h₂éḱwos* (horse)
* Descendants in Modern Languages:
* English: *horse*
* German: *Pferd*
* Spanish: *caballo*
* Sanskrit: *aśva*
* Russian: *лошадь* (loshad')
This shows how the *Proto-Indo-European* word *h₂éḱwos* has evolved into different forms in various languages that descend from Proto-Indo-European.
Other examples:
* *h₁éḱwos* (to hear): English: *hear*, German: *hören*, Russian: *слышать* (slyshať)
* *h₂éḱwos* (to eat): English: *eat*, German: *essen*, Sanskrit: *aśnāti*
Important points to note:
* Reconstruction: These are reconstructions based on studying and comparing words in known Indo-European languages.
* Sound changes: Languages change over time, and words have undergone sound shifts and transformations since Proto-Indo-European.
* No written record: There is no known written record of Proto-Indo-European.
So, while we can't give you an exact example of a Proto-Indo-European sentence or word, these reconstructed examples give us a glimpse into the past and help us understand the relationships between languages.
