1. Introduction

The English lexicon presents significant challenges for non-native speakers, particularly for learners from morphologically rich languages like Romanian. This paper addresses the need for innovative lexicographical tools that integrate traditional dictionary functions with grammatical information and modern ICT capabilities.

2. Core Vocabulary Challenges in EFL

2.1 Contrastive Semantics and False Friends

Romanian learners face particular difficulties with semantic false friends and partial cognates. For example, Romanian "actual" means "current," while English "actual" means "real." These subtle differences require explicit contrastive treatment in learning materials.

2.2 Collocation and Phraseological Structures

English collocations often follow patterns unfamiliar to Romanian speakers. The paper identifies common problematic areas including verb-noun collocations (e.g., "make a decision" vs. "take a decision" variations) and adjective-noun combinations.

2.3 Grammatical Anomalies and Irregularities

Irregular verb forms, plural formations, and comparative/superlative irregularities pose significant memorization challenges. The author argues these should be treated as lexical rather than purely grammatical issues.

2.4 Pronunciation and Spelling Divergences

The non-phonetic nature of English spelling creates additional barriers. The paper documents common pronunciation errors among Romanian learners and suggests systematic approaches to address them.

2.5 Proper Nouns and Cultural References

Proper names, geographical terms, and cultural references require special attention in bilingual dictionaries, as they often lack direct equivalents and carry cultural connotations.

3. The Complex Grammaticized Dictionary Model

3.1 Polyfunctional Design Principles

The proposed dictionary integrates multiple functions: traditional lexical lookup, grammatical reference, pronunciation guide, and collocation dictionary. This polyfunctional approach reduces the need for multiple reference sources.

3.2 Interconnective Approach: Grammar-Semantics Integration

Each lexical entry includes grammatical information presented through an accessible coding system. For example, verb entries specify transitivity patterns, typical complements, and common collocations.

3.3 Accessible Code-System Implementation

A color-coded and symbol-based system indicates grammatical categories, usage frequency, register appropriateness, and common learner errors. This visual coding enhances quick reference and pattern recognition.

4. Technical Framework and Implementation

4.1 Database Architecture and Lexical Fields

The dictionary employs a relational database structure where words are organized into semantic fields and linked through various relationship types: synonymy, antonymy, hyponymy, and collocational patterns.

4.2 Mathematical Representation of Lexical Relations

Lexical relationships can be modeled using graph theory. Each word $w_i$ is represented as a node, and relationships as edges with weights $r_{ij}$ representing relationship strength:

$G = (V, E)$ where $V = \{w_1, w_2, ..., w_n\}$ and $E = \{(w_i, w_j, r_{ij})\}$

Collocational strength between words $w_a$ and $w_b$ can be calculated using pointwise mutual information:

$PMI(w_a, w_b) = \log_2\frac{P(w_a, w_b)}{P(w_a)P(w_b)}$

4.3 Experimental Validation and User Testing

Preliminary testing with 150 intermediate and advanced Romanian learners showed:

• 40% improvement in collocation accuracy compared to traditional dictionaries
• 35% reduction in grammatical errors in production tasks
• Significantly higher user satisfaction ratings for complex entries

Chart Interpretation: User performance metrics demonstrate clear advantages for the grammaticized approach, particularly in productive language tasks. The most significant improvements were observed in collocation usage and grammatical accuracy.

5. Analysis Framework: Case Study Examples

Case Study 1: Verb "Take" Analysis

The framework analyzes "take" through multiple dimensions:

1. Grammatical Patterns: Transitive (take + NP), Phrasal (take up, take on), Idiomatic (take for granted)
2. Collocational Network: take a decision, take responsibility, take time, take place
3. Contrastive Analysis: Romanian equivalents: "a lua" (physical taking) vs. "a lua o decizie" (metaphorical)
4. Error Prediction: Common Romanian learner error: "make a decision" interference

Case Study 2: Adjective "Actual" Contrastive Treatment

The entry explicitly contrasts:

• English "actual" = real, existing in fact
• Romanian "actual" = current, present-day
• Recommended equivalents: current = actual, real = real
• Usage examples highlighting the false friend danger

6. Future Applications and Development Directions

AI-Enhanced Adaptive Learning: Integration with machine learning algorithms to personalize vocabulary presentation based on learner error patterns and L1 interference predictions.

Augmented Reality Applications: Mobile applications using AR to provide contextual vocabulary support in real-world environments, linking words to visual representations.

Cross-Linguistic Database Expansion: Extending the framework to other language pairs following similar contrastive principles, creating a multilingual learning ecosystem.

Natural Language Processing Integration: Incorporating NLP tools for automatic collocation extraction and error pattern detection from learner corpora.
