Of is a very useful and multi-purpose preposition but sometimes, while doing my essay-writing exercises, I am tempted to use of… of… of… of… and the sentence becomes rather overburdened and tangled.
At present my personal record is 4 ofs in a row but as I feel I could do more
The simplest example (just to illustrate my question on a ‘good style’) is with possessive form:
This is the most favourite toy of the dog of Mike[’s?] .
This is the most favourite toy of the Mike’s dog.
This is Mike’s dog’s favourite toy. (or, maybe ‘adjective’s first’ and it should be: This is the most favourite Mike’s dog’s toy. ?)
Which is better - in this particular case?
How much ‘of in-a-row’ do you use normally - two? three? ? When speaking? When writing (…formally, informally) ?
Could you generally recommend me a rule of thumb to follow it and not to overburden my sentences?
