the forms haya cantado, hubiere cantado and hubiera~-se cantado in the period between 1701 and 2023 in Latin American varieties of Spanish. The monograph consists of three chapters. The first two present the history of the compound tenses of the subjunctive mood from Latin to 21st -century Spanish, while the third investigates in detail the frequency of its use between the 18th and 21st centuries in Latin American Spanish. Thus, the first chapter, which covers the period up to the Golden Ages, revolves around the creation of compound tenses whose origin is found in the Latin construction epistulam scriptam habeo. In the second chapter, after familiarizing the reader with the periodization of Latin American Spanish, the use of compound tenses of the subjunctive mood in different Spanish varieties in Latin America between the 18th and 21st centuries is examined, that is, in the period corresponding to modern Spanish. The most typical contexts of use of haya cantado, hubiere cantado and hubiera~-se cantado are analyzed, and it also offers some observations on the frequency of their use in Latin American countries. Chapter three analyzes the frequency of use of haya cantado, hubiere cantado and hubiera~-se cantado between 1701 and 2023, based on data collected in the CORDE, CORDIAM, CREA and CORPES XXI corpora. Likewise, the frequency of use of cantara~-se is examined, which, as indicated on several occasions, primarily competes with haya cantado.The work ends with concluding observations that concisely and briefly summarize the main ideas. |
