The Latin phrase 'fortiter ac fidenter' translates into English as follows: Strongly and boldly. The word-by-word translation is the following: 'fortiter' mean 'bravely' or 'strongly'; and 'fidenter' means 'boldy' and 'confidentely'. Both are adverbs. For the adverb 'fidenter' is formed from the verb 'fidere' meaning 'to believe, confide in or trust', and 'fortiter' from the adjective 'fortis'.
It looks like Latin with the 'fortiter'. It's not Scottish Gaelic.
