34 The Loom of Language by committing to memory the essential particles, and a very small class of exceedingly common words, such as /, hims who, called pronouns (pages 96-102) At the same time we should familiarize ourselves with the less essential paiucles so that we recognize them when we meet them That is to say, we should begin by learning the FORLIGN EQUIVALENTS for the eighty or so most ESSBNIIAL ones, and, since it is always easier to recognise a foreign word we have previously met than to recall it, the ENGLISH EQUIVALLNI for about a hundred and fifty other most COMMON foreign synonyms of this clat,s. How we should choose our basic particles and pronouns, how it is best to set about memorising them, and what we should then do, will turn up later ESSENTIAL GRAMMAR First we have to decide what to do about grammar, and this means that we must be clear about what is meant by the grammar of a language Having a list of words of which we know the usual meaning does not get us very far unless we have knowledge of another kind We cannot rely on the best dictionary to help us out of all our difficulties To begin with, most dictionaries leave out many words which we can construct according to more or less geneial rules from those included in them. A Spaniard who wants to learn English will not find the words father's, fathers, or father^. In their place, the dictionary would give the single word father. An ordinaiy dictionary does not tell you another thing which you need to know It does not tell you how lo arrange words, or the circumstances in which you choose between certain words which are closely related, If a German tried to learn English with a dictionary, he might compose the following sentence. probably will the girl to the shop come if it knows that its sweetheart there be will. A German does not arrange words in a sentence as we do, and his choice of words equivalent to he, she> and it does not depend upon anatomy, as in our own language. So we should have some difficulty in recognizing this assertion as his own way of stating: the girl will probably come to the shop if she knows that her sweetheart will be there There are three kinds of rules which we need to guide us when learning a language, whether to read, to write, to speak, or to listen intelligently We need rules for forming word derivatives,* rules for the * Here and elsewhere derivative means any word denved from some dic- tionary item according to lulcs given in grammar books So defined, its use xn this book is the editor's suggestion, to which the author assents with some misgiving, because philologists employ it m a more restricted sense The justification for the meaning it has in The Loom is the absence of any other explicit word for all it signifies*
