## Details

The abbreviations_ objects are character vectors of abbreviations. These are words or phrases containing full stops (periods, ambiguous sentence terminators) that require special handling for sentence detection and tokenization.

The original lists were compiled by the Unicode Common Locale Data Repository. We have tailored the English list by adding single-letter abbreviations and making a few other additions.

The built-in abbreviation lists are reasonable defaults, but they may require further tailoring to suit your particular task.
