well with language techniques, i have quite a bit in my book so ill type some stuff up. It's really basic and choppy, jsut basic notes, but i think you could expand on a few points quite a lot.
The fact that it is a memoir allows for reflection and reminiscent tone and an understanding of events. It allows Gaita to look back on memories from his childhood and see htem in a new light, the text could most definatly be considered sometimes romanticised.
It's written in retrospect - eulogy, this purpose is clearly exposed in the Gaita clearly makes the book about his father with little information about his personal life later, all/most events involve Romulus.
The book focuses on events that illustrate his fathers temperament and allows an evaluation of Romulus and Gaitas' bond
It has a certain lyrical quality, which is evident in his lush landscape imagery.
The lack of dialogue and direct quotes allow the responder to feel more included within the text
The simplistic/ precise and effective language/ description and the fact that Gaita does not embellish events to much which makes the book an easy, simple and beutiful read communicating the main ideas a lot clearer.
Symbolism and motifs present through out the book - mental illness, setting, connection with animals and land, family
Central irony - the memoir allows Gaita to attempt to search for his own identitym autobiographical
analytical and rather detached - philosophical, Gaitas personal context (a main contributer to ones sense of belonging) influences his approach to writing the novel. - Gaitas level of education is evident and conversations rarely border on colloqiual
hope that all helped!!
