ศาสตร์

• ศาสตร (sàat-dtrà-) — prefix
• ศาสตรา
• สาตร — obsolete

Borrowed from Sanskrit शास्त्र (śāstra, “science”), from the root verb शास् (śās, “to order; to command; to direct”), whence also ศาสนา (sàat-sà-nǎa, “religion”).

Cognate with Khmer សាស្ត្រ (saah), Lao ສາດ (sāt), Pali sattha.

ศาสตร์ • (sàat)

1. (chiefly in compounds) science; field or branch of knowledge; -ology.

When a field is suffixed with บัณฑิต (ban-dìt, “bachelor”), มหาบัณฑิต (má-hǎa-ban-dìt, “master”), and ดุษฎีบัณฑิต (dùt-sà-dii-ban-dìt, “doctor”), the prefix form ศาสตร (sàat-dtrà-), without the killer mark, is used instead.
