When not in English, university mottoes are usually in Latin, reflecting the origin of universities in mediaeval institutions in which Latin was very prominent.
Here are mottos of various colleges and universities in the United Kingdom.
University of Aberdeen, Aberdeen, Scotland: initium sapientiae timor domini
'The fear of the Lord is the beginning of wisdom'.
The phrase is found a number of times in the 'wisdom' portions of the Bible, including Proverbs 1:7, 9:10, Psalm 111:10 and Job 28:28.
Bolton Institute of Higher Education, Bolton, UK: sapientia superat moras
