* For age or stage of development (e.g., advanced age, advanced studies):
* Scottish Gaelic: `adhartach` (this implies progress or being further along) or `aosta` (specifically for age, meaning old or elderly). For studies, `air astar` (far along) might also work.
* Irish Gaelic: `forásach` (progressive, advanced), `sean` (old), or `ar aghaidh` (ahead, further on)
* For a skill or technology (e.g., advanced technology, advanced driving skills):
* Scottish Gaelic: `adhartach` (advanced, progressive), `fiosrach` (sophisticated), or a phrase like `air leth adhartach` (particularly advanced)
* Irish Gaelic: `forásach` (progressive, advanced), `sofaisticiúil` (sophisticated), or a phrase similar to the Scottish Gaelic example.
* For a disease (e.g., advanced cancer):
* Both Scottish and Irish Gaelic would likely use descriptive phrases rather than a single word. For example, you might say something like (Scottish Gaelic) `aillse air astar` (cancer far along) or (Irish Gaelic) `ailse ar aghaidh` (cancer progressing).
Therefore, there's no single perfect equivalent. You need to choose the word or phrase that best reflects the specific meaning of "advanced" in your sentence. Providing the sentence you want to translate would allow for a much more accurate and helpful response.
