begining to get frustrated with the genitive in as much that I find it difficult to tell the difference between the plural and singular. If anyone has a Genitive Single and Plural For Dummies explanation please help. I understand some of it but this example is the kind that throws me off. I looked and saw Na but knew this doesn't necesarily mean it's plural but then I see the plural of schools without eclipsis and think Plural! but I was wrong. Surely it doesn't mean that you have to check every single word you learn to see how it is used,their must be a pattern,surely.
Irish nouns have five declension patterns; a noun’s declension is determined by its genitive singular form, and each declension can form its plurals (i.e. nominative plural and genitive plural) in different ways, depending upon the noun. In the case of scoil, its genitive singular is scoile ; because the genitive singular ends with an e, it’s a second declension noun. Second declension nouns can form their plurals in different ways; in the case of scoil, the plural is “strong” (i.e. its nominative plural form and its genitive plural form are identical): scoileanna. There are patterns, but the patterns have to be learned.
While all the examples of timpeall in https://www.teanglann.ie/en/fgb/Timpeall_ seem to be suggesting "around", either literally or figuratively, https://www.focloir.ie/en/dictionary/ei/about#about__4 does recognise an equivalence for "about" as in "he spent all day running about the office: chaith sé an lá ar fad ag rith timpeall na hoifige" or "he ran about in the garden: rith sé timpeall an ghairdín", amongst others.
