In this paper I take Freud's first published book, his monograph 'On aphasia', and look carefully at the terms he used in it, suggesting some later reappearances of the conception expressed by that particular word. There are several words that entered the analytic vocabulary with the monograph, indicating, as Stengel proposed, that the book 'laid the foundations of psychoanalysis'.

I review the following words: association, divided attention, cathexis, complex, connection, physiological correlate, impulse to speak, memory-image, primary, representation, self-observation, spontaneous speech and transference.
