I have recently come across the terms subjective genitive and objective genitive, but I don't fully understand them.
From what I have read, an example might be 'the love of God', as in 'the love of God will see you through dark times'. In this phrase, the 'lover' (who would be the subject in a simple sentence like 'God loves you') is 'God' and is preceded by the preposition 'of'. In a language like Latin or Sanskrit, it would be placed in the genitive case. This is the subjective genitive.
Meanwhile, in 'the fear of God', as in 'the fear of God is the beginning of wisdom', the 'feared' (who would be the object in a simple sentence like 'you should fear God') is God and is preceded by the preposition 'of'. This is the objective genitive.
It seems that it is also possible to construct an example where it could be either subjective or objective in isolation. For example, 'the love of your mother', where the mother could be the lover, as in 'the love of your mother will see you through dark times', or the mother could be the loved, as in 'the love of your mother is the deepest emotion'. (Well I think that sounds very contrived.)
That's my research effort, but the problem is, it's not a definition, is it? It's some examples even I don't understand very well and some waffle.
Can anyone define these terms and are there any techniques we can use to distinguish between the subjective and objective genitive?
