Old English (OE) has traditionally been regarded as an extraordinarily complex language, for its intricate syntactic and morphological relations remain a conundrum for many historical linguists.This explains the substantial number of manuals which primarily focus on the basics of grammar (Mitchell and Robinson 1992; Hog 2012;Fulk 2014).Nevertheless, for those enthusiasts who would like to deepen their insight of Old English structures, Ojanguren López book constitutes a stimulating work which explicitly delves into one of the most elaborate aspects of syntax and semantics: the competition on the complementation of OE aspectual and manipulative verbs, namely, the ones that correspond to contemporary English aspectual end, try and fail, along with manipulative forbid, hinder and refrain.This research also addresses the question of "the rise of serial verb constructions in English" (Ojanguren López 2024, 17) and provides some clarification on the semantics of the verbs linked to complementation patterns, which represents a valuable addition to prior contributions (Callaway 1913;Mitchell 1985;Molencki 1991;Denison 1993;Martín Arista 2022).The aforementioned monograph is divided in nine chapters, which facilitates the comprehension of the matter of study, as it is presented sequentially and includes a well-defined methodology which is supported by the theoretical underpinnings of the research.Thus, chapter one overviews the major focus of the undertaking as well as its analytical structure, and contextualises the complementation patterns of verbs of aspect and manipulation in Old English within its most recent framework.Once the fundamentals have been established, chapter two underlines the relevance of the work that has been carried out considering several dimensions (synchrony, diachrony, typology), which contribute to a comprehensive approach of the objects of research.Furthermore, the lexicographical and textual sources specified in said chapter include dictionaries, lexical databases, grammars, translations, and lemmatisers.In order to describe the competition existing on the complementation of Old English verbs, the Role and Reference Grammar (RRG) and its Interclausal Relations Hierarchy (Van Valin and LaPolla 1997;Van Valin 2005) are proposed, for its "model of the interaction between morphology and syntax, including constituents and operators" is paramount for a language such as Old English (Ojanguren López 2024, 26).Additionally, several works on the clausal complementation of verbs are revisited to discuss different types of competition (Callaway 1913;Denison 1993;Molencki 1991;Los 2005) while introducing nominal complementation and verb serialisation as the innovative elements of the study.As a means to expand the foundations sustaining the analysis on OE verbal complementation, Ojanguren López reviews in chapter three the most relevant parts of the theory of RRG, as the former is central for the consideration of semantic and pragmatic categories in syntax, and for the concern of cross-linguistic validity.The book also devotes special attention to lexical representation, semantic roles and macroroles, which play a crucial role in the association of semantics and syntax, as well as the notion of Aktionsart (Brugmann 1922), for it constitutes "the semantic representation of the sentence" (Ojanguren López 2024, 37).Additionally, grammatical relations embodied in the function of Privileged Syntactic Argument (PSA) and clause structures represented by the Layered Structure of the Clause (LSC), which distinguishes multiple forms of complex referential clauses, complete RRG theory and indubitably help the reader understand the basis for the subsequent study, reinforced by the concepts of juncture and nexus acting as the main aspects of the theory of complex sentences.Chapter four, in turn, intends to become a further contribution towards "a more semantically oriented syntax of Old English" (Ojanguren López 2024, 57), hence it revolves around preceding research in the structural-functional analysis of Old English (Martín Arista 2000a, 2000b, 2020) with the aim of applying these earlier advances to the linking of semantics and syntax proposed by RRG.To successfully accomplish this, terminological remarks such as Verb Classes and Alternations (Levin 1993), linking and its
