Note 78 — Chapter VII

Writers on infant psychology differ as to the time when words are first understood by infants. Doubtless it varies in individual cases, and is always more or less difficult to determine with accuracy. But all observers agree—and every mother or nurse could corroborate—that the understanding of many words and sentences is unmistakable long before the child itself begins to speak. Mr. Darwin’s observations showed that in the case of his children the understanding of words and sentences was unmistakable between the tenth and twelfth months.
